Controlled Environment Agriculture by Shrubs

hey shrubs. thanks for your long, and detailed journal. has proven helpful to me as i'm just switching to coco after using sunshine mix for about 3 years. decided to go with the canna combo and was wondering about a few things. i've read your journal over the last few years and have searched back now but cant seem to find a definitive answer about your water. i think your using ro/ di and not using calmag. is this true? i have pretty hard well water and am trying to decide whether or not to mix it 50/50 or not. i know the canna site says the nutes are formulated for about 200ppm of minerals. makes me think blank water is not the way to go, but you seem okay using it? from reading around, calmag seems to be necessary for most using ro and canna. could you tell me your thoughts? i know its about reading the plants and all, just trying to get a step ahead. also when wetting the coco for the first time, do you just use a very diluted nute mix? thanks so much for your time

Sorry for huge delay. I think cal/mag is necessary here and there for RO. I don't DI. I do use
cal/mag but not every feeding. When first feeding in coco, I use 2 mL / liter, or roughly 7 mL / gallon of A and B.
