I was having problems with my nutes and cal/mag in particular. I know it isn't rocket science, but I was messing something up.
I went to a one part nutrient and things improved quit a bit.
I use RO water.
This is what's in it. dyna gro fp 9-3-6. See how much cal and mag it has? That's how much my coco likes, not the "extra" I was giving with gh nutes I didn't understand. Maybe you can learn from my dumb.
I add 50 ish ppm of armor Si 0-0-4 ( which is silica and K. I end up with a 3-1-3 npk ratio basically.
Water to 20% runoff when you water. Droopy plants are usually too wet or have root problems in my limited experience.
I'm feeding 4x a day atm about 300ml a feed, just enough to get the right runoff. When my plant was smaller I only fed it once a day, sometimes I didn't need to feed it because it was still very wet when my temps were down.

My coco is brick hydro crunch from amazon, I washed it and buffered with cal/mag and then let it sit in 200ppm nutes solution for a few days.
I'm trying this next.
