First Grow Hulkberry

The ladies seemed to recover well from the topping and are growing quickly. I out our 5th plant in some soil because I can't just let her die. Ph has been around 5.9 to 6.0 throughout the week, I add ph down when it creeps to 6.2. I forgot to mention im using ro water. My tap water had a starting ppm of 450 and that was going to complicate my efforts. I've noticed that after adding nutrients, cal mag and hydrogaurd my ph is right at 5.8 after mixing and resting for 12 hours. (I used fish tank heaters to bring the temperature up to 67 degrees before cycling water). My big mistake this week was putting some nutrient water in a spray bottle and getting some water on the leaves. "Betty" the slower plant in hydro has leaf damage and there are a handful of spots on a larger fan leaf on "lily". Otherwise it may be a mag deficiency for Betty. Being small and ph above 6.0 she may not be getting it. Or she's just more sensitive to the nutrient levels.
