Excel Calculation Styles – Dr. Trippers Stuff

apply a calculation style in Ecel

In Excel, you can apply a **calculation style** using built-in or custom formatting options. Here are a few ways to do this:

### **1. Use Built-in Cell Styles**
1. Select the cells containing formulas.
2. Go to the **Home** tab.
3. Click **Cell Styles** (in the **Styles** group).
4. Choose **Calculation** from the list.

This will format the selected cells with a distinct style, making them stand out.

### **2. Apply Conditional Formatting** (Dynamic Highlighting)
If you want to highlight all formula cells dynamically:
1. Select the entire worksheet (**Ctrl + A**).
2. Go to **Home > Conditional Formatting > New Rule**.
3. Choose **Use a formula to determine which cells to format**.
4. Enter the formula:
“`
=ISFORMULA(A1)
“`
5. Click **Format**, select a color or style, and click **OK**.

### **3. Manually Customize Formula Cells**
– Use **Bold** or **Italic** for formula cells.
– Apply a **color fill** (e.g., light yellow) for easy identification.
– Use **Borders** to separate calculation sections.

is baking soda any good for plants
Yes, baking soda (sodium bicarbonate) can be beneficial for plants in certain situations, but it should be used with caution. Here’s how it can help:

### **Potential Benefits:**
1. **Fungal Disease Prevention** – A mild baking soda solution can help prevent powdery mildew and fungal infections on plants like roses, cucumbers, and tomatoes.
– **Recipe:** Mix **1 teaspoon of baking soda** with **1 quart of water** and a few drops of dish soap. Spray on affected leaves.

2. **Pest Control** – It can deter some insects like ants and aphids when sprinkled around the base of plants.

3. **Soil pH Adjustment** – If the soil is too acidic, small amounts of baking soda can help neutralize it. However, it is not a substitute for agricultural lime.

### **Potential Risks:**
– **Too much can harm plants** – Excess baking soda can raise sodium levels in the soil, which can be toxic to plants.
– **May alter soil pH unpredictably** – It works best for small adjustments but is not a long-term solution for acidic soils.
– **Can burn leaves** – If applied in high concentrations, it may damage plant tissue.

### **Best Practices:**
– Always **test on a small area** before applying widely.
– Use sparingly and only when needed.
– Avoid overuse, especially in soils with already high sodium content.

Sativa
For **Sativa** plants (Cannabis Sativa), baking soda can be used **cautiously** in the following ways:

### **1. Fungal Prevention (Powdery Mildew, Mold)**
Sativa plants, especially in humid environments, are prone to **powdery mildew** and **bud rot**. A mild baking soda spray can help prevent fungal growth.

**Solution:**
– Mix **1 teaspoon of baking soda** with **1 quart of water**.
– Add a few drops of **dish soap** or **neem oil** to help it stick.
– Spray lightly on leaves (avoid buds).
– Apply **once a week** as a preventative measure, preferably in the evening.

### **2. Soil pH Adjustment** (Use with Caution)
Sativa plants thrive in slightly acidic to neutral soil (**pH 6.0–7.0**). If the soil is **too acidic**, small amounts of baking soda can help raise the pH.

**How to Apply:**
– Dissolve **½ teaspoon of baking soda per gallon of water**.
– Water **sparingly** and test the soil pH before reapplying.
– Too much can cause nutrient lockout, affecting growth.

### **3. Pest Control (Ants, Aphids, Spider Mites)**
Baking soda is **not the best** insecticide, but it can deter ants and some pests when mixed with sugar as a bait.
– For aphids/spider mites: Use **neem oil or insecticidal soap** instead.

### **Cautions:**
– **Never spray directly on buds**—baking soda can affect taste and quality.
– **Avoid overuse** in soil, as it can lead to nutrient imbalances.
– **Test soil pH** before using, as cannabis prefers slightly acidic conditions.

Nutrients
For **Sativa** plants, proper nutrient balance is crucial for healthy growth, high yields, and potent cannabinoids. Here’s a breakdown of the essential nutrients needed throughout different growth stages:

—

### **1. Primary Nutrients (Macronutrients)**
These are the **most important** for Sativa plants:

#### **Nitrogen (N) – Vegetative Growth**
– Supports **leaf & stem development**.
– Deficiency: Yellowing leaves, slow growth.
– Sources:
– Organic: **Blood meal, fish emulsion, compost tea**
– Synthetic: **Veg-specific nutrients (NPK 3-1-2 or 5-2-2)**

#### **Phosphorus (P) – Root & Flower Development**
– Essential for **root strength** and **bud formation**.
– Deficiency: Stunted growth, purple stems.
– Sources:
– Organic: **Bone meal, bat guano, rock phosphate**
– Synthetic: **Bloom nutrients (NPK 1-5-4 or 0-10-10)**

#### **Potassium (K) – Overall Plant Health & Bud Density**
– Improves **resistance to stress**, **trichome production**, and **bud quality**.
– Deficiency: Brown leaf edges, weak stems.
– Sources:
– Organic: **Wood ash, kelp meal, banana peel tea**
– Synthetic: **NPK with high K ratio (0-5-10 or 2-7-15)**

—

### **2. Secondary Nutrients (Micronutrients & Additives)**
While needed in **smaller amounts**, these are essential for maximizing Sativa growth:

– **Calcium (Ca)** – Strengthens cell walls (Use **dolomite lime, gypsum**).
– **Magnesium (Mg)** – Essential for chlorophyll production (Use **Epsom salt, Cal-Mag supplements**).
– **Sulfur (S)** – Aids enzyme activity (Use **langbeinite, gypsum**).

—

### **3. Feeding Schedule (General Guide for Sativa Strains)**

—

### **4. Organic Boosters for Resin & Terpenes**
– **Unsulfured Blackstrap Molasses** – Provides carbohydrates and micronutrients.
– **Seaweed/Kelp Extract** – Enhances stress resistance and terpene production.
– **Aloe Vera & Coconut Water** – Supports microbial life and nutrient uptake.

—

### **5. Water & pH Considerations**
– **Optimal pH for Sativa in Soil:** **6.0 – 7.0**
– **Optimal pH for Sativa in Hydroponics:** **5.5 – 6.5**
– Always **adjust pH** after mixing nutrients to prevent lockout.
