I'm using GH Maxigro and CalMag on my hydro Dutch Buckets. The bag recommends 1-2 tsp per gallon. I mix 1 tsp per gallon with 3 ml of CalMag and that gets me to about 600ppm, and she seems to like that so far.
Is that with R/O?
I'm using tap water with a cheaparticular chlorine filter and my ppm is 220/240
I've been reading about whats in my water' and was told that 61mg/l of calcium & 9.8 mg/l of magnesium was enough to sustain my plants without causing deficiency?
However I have had some deficiency so I fed them 3ml of plant magic magnacal+ & a small pinch of Epsom at a ratio of 1/4tsp per 10 litre mix?
I'm finding my feet with this coco feeding and I'm sure there will be some bumps along the way?
