@Metatronix, how much calmag would you add for such a solution? 20 ppm?50?

@Metatronix, At first I thought that I have very weak bloom fertilizers. I decided that it was a lack of phosphorus, but the addition of bloom did not help. I think that this is a block of calcium due to an overdose of phosphorus and potassium. Now the leaves are showing signs of calcium deficiency. I made a new solution with two or three weeks old tap water. what do you think? tap water is 200 ppm. I don't have a Сalmag. i have calcium nitrate. chelated calcium. and magnesium sulfate. but I really don't like magnesium sulfate)) I think everything will be fine. Now the ppm of the solution is about 400 ppm. pure water 200 ppm. I think that tomorrow I will try to spray with calcium chelate waiting for new measuring tools😒

I'm not sure if it's Calcium blockage in DWC the plant will lack CalMag even if you use nutrients for hydroponics ...to be honest i only used Atami and Jungle indabox nutes ...but i add CalMag.

@ArthurStotch, A bit stretchy/spacey due to weak lighting, but revegging been an interesting process to watch for sure.
