Durban Poison DWC ScrOG

WEEK 2 VEGETATION This week is basically a repeat of week 1. Still using the same reservoir water from last week. On Sunday, roots started showing at the bottom of the net cup. I let her continue to stretch up some this week. This will allow me to further back fill the net cup with hydroton, to block out light from entering the reservoir. She is showing signs of hunger. Now that she has started growing a few roots down into the reservoir, I'll start next week with a stronger reservoir feed and move her under better lighting. My Nutrient Inputs: To keep costs down, I will be using a powdered nutrient ( 5-12-25 Tomato Blend ) by MasterBlend, plus Epsom Salt (Magnesium Sulfate), and Calcium Nitrate. This is essentially the Jack's 3-2-1 method ( for those of you who are familiar with it ), except I'm using MasterBlend, a more readily available manufacturer in Canada. I mixed up two concentrated stock solutions to make a Part A and Part B, for fast, easy reservoir mixing. The formula is roughly 3 parts MasterBlend, 2 parts Calcium Nitrate, and 1 part Epsom Salt, all measured by weight. To Make Part A - Start with a 4 Liter bottle of distilled water. Remove about 2 liters and set aside. Mix in 720 grams of MasterBlend and stir until fully dissolved. Then mix in 240 grams of Epsom Salt (magnesium sulfate) and stir until fully dissolved. Now add back enough distilled water, that was set aside earlier, to make 4 liters of stock solution. Store in a cool, dark place. Light proof containers are advised. To Make Part B - Start with a 4 Liter bottle of distilled water. Remove about 2 liters and set aside. Mix in 500 grams of Calcium Nitrate and stir until fully dissolved. Now add back enough distilled water, that was set aside earlier, to make 4 liters of stock solution. Store in a cool, dark place. Light proof containers are advised. Part A gets mixed into the reservoir, followed by part B. Equal amounts of Part A and Part B are typically used. These stock solutions will make several hundred gallons ( depending on your dosage strength ) of mixed reservoir nutrients, inexpensively.
