Cioreanswered grow question 6y ago Hey Jimmi, look, I grow in coco and during the first week I only give 1 ml of nutrients. For the roots, with pH 6. Starting from the second week, I add 0.5 per L of calmag, 0.5 of A+B, and then I gradually increase. But when it's small in the first week, I prefer to go slow, and depending on how I see the plant (color), I water or not (with fertilizer) because a lot of salt builds up. Also, when I use a small pot, I go slower with the amounts of nutrients. A lot of salt accumulates. And another thing, at least I do it THIS WAY and I find it wonderful. I keep the pH at 6 throughout the entire vegetative and flowering period and I've never had problems. A hug, my friend, I hope I’ve helped you with my limited experience.
