Plant leaf curling causes – Dr. Trippers Stuff

A Marijuana plant, look a mild green, leaves are slightly rolling lengthwise. Is this indicative of watering, food, light or just normal

Ah, the classic “Why is my weed being weird?” mystery.

### Let’s decode your clues:
– **Mild green color**
– **Leaves slightly rolling lengthwise (taco-ing)**

That’s not normal-normal, but not full panic mode either.

—

### Possible Causes:

#### 🌞 **Light Stress (Most Likely)**
When leaves **roll or taco lengthwise**, it’s often a sign the plant is **trying to reduce surface area** exposed to intense light or heat.
– Check if it’s directly under a strong light source.
– If using LEDs, make sure they’re not too close.
– Try raising lights or dimming intensity.

#### 💦 **Underwatering**
Leaves may also curl or look slightly limp and washed-out if the plant’s **a bit thirsty**.
– Stick your finger in the soil or pot medium.
– If it’s dry an inch or two down, give it a drink.

#### 🧂 **Nutrient Deficiency or Lockout**
Mild green could mean **not enough nitrogen**, or an imbalance (like pH issues) causing lockout.
– Check pH levels of water/runoff (ideal range: 6.0–6.5 in soil).
– Ensure you’re not overfeeding or underfeeding.

#### ✅ **Sometimes, It’s Just the Strain**
Some phenotypes or strains have naturally lighter foliage and mild leaf curl tendencies. Especially sativas.

—

### TL;DR Diagnosis Flow:
1. **Too much light?** → Raise or dim.
2. **Dry soil?** → Water.
3. **Nutrients/pH off?** → Test runoff.
4. **Strain-specific?** → Compare to known photos of your cultivar.

If it’s otherwise perky and growing, it’s whispering for a tune-up, not screaming for help. Want to send a photo and I’ll Sherlock this thing further?
I notice the tips of the leaves are brown
Ah—**brown tips**, the universal plant distress signal. Now we’re getting warmer (possibly literally).

Let’s triangulate:

—

### With your symptoms:
– **Mild green color**
– **Leaf taco-ing (curling lengthwise)**
– **Brown tips**

—

### 🎯 Most Likely Culprit: **Nutrient Burn (Nute Burn)**
– Classic brown tips = **too much food**, especially **nitrogen, potassium, or salts**.
– Leaves taco-ing adds a possible **heat/light stress** overlap.

—

—

### 🧪 What to Check:
1. **Runoff EC or PPM (TDS)**
If using synthetic nutes, check if salt levels are high in the runoff.
2. **pH**
Too high/low pH = nutrient lockout = deficiencies + burn at same time.
Soil sweet spot: **6.2–6.5**
3. **Feeding Schedule**
Did you recently up the dosage? Or use a “bloom booster” or “super” soil?

—

### 🧯What To Do:
– **Flush** with clean, pH-balanced water if runoff ppm is high.
– **Dial back nutes** to ½ strength for the next couple feeds.
– Check lights: if it’s hot near the canopy, raise them a few inches.

—

### 😎 Rule of Green Thumb:
> **Brown tips = too much. Yellowing = not enough. Curling = heat, light, or root stress.**

It’s talking. You’re listening. You’ll save it.

It looks like nitrogen burn to me
Good eye, Doc Tripper. **Nitrogen burn** fits the case like a glove dipped in fertilizer.

—

### 🔎 Let’s do a spot-check against nitrogen toxicity symptoms:

#### ✅ **Leaf tips turn brown or burnt-looking**
Classic overload indicator.

#### ✅ **Leaves are overly dark green**
You said “mild green,” but in early toxicity, this might not show full force yet—or the plant could be recovering.

#### ✅ **Leaf clawing or curling**
Check: are the **tips curling downward like talons**? That’s the “nitrogen claw.”

#### ✅ **Lower leaves more affected**
Nitrogen hits from the bottom up (mobile nutrient).

—

### 🧪 Confirmation Checklist:
– Fed with a high-nitrogen mix recently?
– Using slow-release soil (like Miracle-Gro)? Sneaky nitrogen bombs.
– No signs of pests or major pH drift? Then this is just overzealous feeding.

—

### 🧯 How to Fix Nitrogen Burn:
1. **Flush** with pH-balanced water (6.2–6.5 for soil) — enough to get runoff.
2. **Pause feeding for 1–2 waterings.**
3. When resuming: **cut nitrogen-heavy nutes in half.**
4. Trim off fully crisped tips if they’re dried out — cosmetic, but helps redirect energy.

—

### 🧠 Pro Tip:
If you’re in **veg**, the plant will bounce back fast. If you’re in **flower**, nitrogen toxicity can delay or weaken bud development. Cut back *more* aggressively in bloom.

5-5-20
Ah—**5-5-20**?

Well then, we’ve got a case of **high potassium** with **low-to-moderate nitrogen and phosphorus**. That **does *not*** scream nitrogen burn… unless something weird is going on under the hood.

Let’s dig deeper:

—

### 📦 What “5-5-20” Tells Us:
– **N (5%)** – Mild, unlikely to cause nitrogen toxicity *on its own*.
– **P (5%)** – Enough for root and flower support.
– **K (20%)** – Heavy potassium dose, typical for *late flowering* formulas.

—

### 🚨 So, if you’re seeing nitrogen burn symptoms (clawing, dark waxy leaves, brown tips), but using **low-N** feed:

**One of these is probably true:**

#### 1. 🔬 **Salt Buildup from Repeated Feeding**
– Even if the mix is mild, salts can accumulate.
– Especially true if you’re not getting runoff or using coco.
– **Test runoff EC/PPM** to confirm.

#### 2. 🧪 **pH Lockout Causing Confused Signs**
– If the pH is off, nitrogen might not be getting absorbed → plant signals deficiency.
– But salts (especially potassium) build up in the root zone, causing burn-like symptoms.
– So you get **brown tips + curl, but pale or weird green** = confused toxicity/deficiency.

#### 3. 🌱 **Residual Nitrogen in Medium**
– If you started with rich soil (e.g., amended or time-release), there may be leftover N.

#### 4. 💣 **Something Else Is Spiking N**
– Using compost teas? Fish emulsion? Cal-Mag with N?
– Sneaky nitrogen often hides in additives.

—

### ✅ What You Should Do:
1. **Flush** (gently): Use 2–3x pot volume of pH’d water and check runoff EC and pH.
2. **Check All Inputs**: Even low-N formulas can build up with frequent feeding.
3. **Let It Dry, Then Reset**: Give plain water next time. Resume at ½ strength feed once plant perks up.
4. **Trim Damaged Leaves**: Only if they’re mostly toasted—don’t remove salvageable ones.

—

If you’re flowering, 5-5-20 is a good general ratio—just maybe too often or combined with hidden N. If vegging, though? You’re starving it for N, ironically.

I am asking is the mix 5-5-20 best for vegetative stage
Ah! Got it now—you’re asking if **5-5-20** is a good nutrient ratio for the **vegetative stage**.

### 💥 Short answer:
**Nope. 5-5-20 is NOT ideal for veg.** It’s actually closer to a **late bloom** or **ripening** formula.

—

### 🧪 Why it’s wrong for veg:

In veg, your plant wants to **build body mass**, which means it craves **more nitrogen** than anything else. Potassium is helpful, but not at *quadruple* the nitrogen level.

—

### 🔧 Better Veg Ratios:
Look for something like:
– **3-1-2**
– **4-2-3**
– **10-5-5**
Think: **High N**, moderate P, decent K.

—

### 🧠 What happens if you veg with 5-5-20?
– Stunted or slow leaf growth
– Possible nitrogen deficiency over time (light green or yellowing leaves)
– Overaccumulation of potassium can **lock out other nutrients**, especially calcium and magnesium
– Wasted potential — like feeding a teenage bodybuilder nothing but bananas

—

### ✅ What To Do:
If you’re early in veg, **switch to a higher-N grow formula ASAP**.
If you’re transitioning to flower soon, you can begin tapering toward that 5-5-20, but **don’t lean on it too early**.

SOil. My obsveration of nitrogen burn on the tips of the leave not correct?
Ah, now we’re zeroing in.

You’re in **soil**, running a **5-5-20**, and seeing **brown tips** — your instinct said *nitrogen burn*, but the numbers say otherwise.

### 🎯 Final Verdict:
Your observation of **nitrogen burn is likely incorrect**, **but your instincts about burn are right** — it’s probably **salt or potassium burn**, not nitrogen.

—

### 🧪 What’s *actually* happening:
– **5% nitrogen** in soil isn’t enough to burn unless there’s leftover N from:
– Rich base soil (like Ocean Forest, Happy Frog, etc.)
– Previous high-N feeds
– Additives (like Cal-Mag, fish emulsions, etc.)
– **20% potassium**, however, **can easily cause tip burn**, especially in:
– Young veg plants
– Plants not yet using heavy K
– Unflushed pots (salt buildup)

—

### 🌱 In Soil, This Is Common:
Burned tips ≠ always nitrogen
Tip burn in soil almost always means:
– **Overfeeding**
– **Salt accumulation**
– **Potassium toxicity**
– **pH imbalance causing lockouts**

And the **mild green** you’re seeing could even be an early nitrogen *deficiency*, oddly enough, due to the *wrong NPK balance*.

—

### ✅ What to do now:
1. **Flush** gently with pH’d water (6.3–6.5) if you haven’t in a while.
2. **Switch to a veg formula** — something with higher nitrogen (e.g., 10-5-5 or 4-2-3).
3. Observe new growth — ignore old damage.
4. Consider top-dressing with compost or worm castings for a gentle N boost if you want to stay organic.

—

### TL;DR:
You saw the **symptom correctly**, just misattributed the **culprit**.
It’s burn, yes. But potassium burn or salt stress — **not nitrogen burn** from that ratio.

Keep watching new growth — that’s the real lie detector.
NO. Forget th mix. Lets go back to the original pic. Start from scratch i do not know anything more about this plant but the image. I am jsut guessing
Perfect—back to baseline. You’re looking at a marijuana plant with:

– **Mild green color**
– **Leaves curling/rolling lengthwise (taco-ing)**
– **Brown tips**

You’re asking: *What does this likely mean, without any assumptions?*

—

### 🧠 Diagnosing From Scratch (No Mix Info):

#### 1. **Leaf Curling (Taco-ing)**
– **Most commonly caused by:**
– **Heat stress** (too close to lights or hot environment)
– **Low humidity** (especially under strong lights)
– Sometimes early sign of overfeeding or wind burn
– Plant rolls leaves to reduce surface area—like putting on sunglasses

#### 2. **Brown Tips**
– **Classically caused by:**
– **Nutrient burn** (often from salts building up in soil)
– **Root stress** (too much water, too little oxygen)
– Could also be pH imbalance leading to poor nutrient uptake and secondary damage

#### 3. **Mild Green Color**
– Not dark green (which could mean excess N)
– Not yellowing (which screams deficiency)
– Suggests plant is *under mild stress*, not in crisis
– Could be minor nutrient imbalance
– Could be environmental (temp/humidity)

—

### 🔍 Overall Assessment (Image-only, No Assumptions):

– **Most likely causes:**
1. **Environmental stress**: heat + low humidity = taco + browning
2. **Slight overfeeding or salt buildup**: just enough to tip the edges
3. **Possibly both**: compounding stress signals
– **Less likely, but possible**: early root rot or bad soil pH

—

### ✅ Smart Next Steps:
– **Check environment first**:
– Temp: should be 70–85°F (21–29°C)
– Humidity: 50–70% in veg, 40–50% in flower
– Light distance: hand-test for heat; too hot = too close
– **Then soil check**:
– Moisture: is it staying wet too long? roots suffocating?
– Flush with pH’d water if plant was recently fed or overfed

—

No need to jump to nitrogen. Curling + tips = likely environmental + salt stress combo. If you can share the pic, I’ll confirm or kill that guess with flair.
Tucson, AZ outdoor – definitely low hunidity.
Ah! Tucson. Outdoors. Game-changer.

You’re dealing with:

### ☀️ **Full desert sun**
### 🌵 **Very low humidity**
### 🔥 **High daytime temps**
### 💨 Possibly wind, too

—

### 💡 Given that:
– **Leaf tacoing** = classic response to **intense sun + dry air**.
The plant’s trying to conserve moisture and shield stomata.

– **Brown tips** = could be:
– **Desiccation (drying out)** of the leaf edges from the heat
– **Salt/mineral buildup** from hard Tucson water (very common)
– Light nutrient burn if you fed recently — but less likely if you didn’t

– **Mild green** = not a disaster, but she’s not in her happy place either.

—

### 🧪 Tucson Twist Factors:

—

### TL;DR:
Yes—greenhousing your avocado is a **viable and excellent plan** in Kentucky. Once it hits 3–4 feet, the greenhouse becomes your avocado’s winter condo.

Want help designing a simple avocado-friendly greenhouse layout or choosing your first cold-hardy cultivar?
The air never gets bone dry here.
Ah—nice clarification. You’re right: **Southern Kentucky winters** aren’t Tucson-dry. They’re more **cold and damp**, especially with all that Appalachian air and seasonal rain.

—

### So for your avocado:

#### ✅ **Humidity’s not the problem**
– You *don’t* need a humidifier or misting system in your greenhouse.
– In fact, **too much humidity** + poor airflow = fungal party (root rot, mildew, etc.)

—

### 🔧 Adjusted Greenhouse Priorities:

—

### Optional Bonus:
If your greenhouse is **attached to a building** (south-facing wall), you’ll get **free thermal mass** and added protection—perfect for overwintering avocados.

—

### TL;DR:
Kentucky air’s fine—your avocado’s not craving a jungle. Just keep it warm, dry (at the roots), and ventilated. Let the rain humidify, not saturate.
