Here is what I could find on my water.
I'm feeding twice a day.
Before, I was trying a powder nute mixed in with coco/soil, but I had bad results, I threw away many, many plants.
So I stopped repeating the same thing over and over and expecting different results and tried hydro, these plants are the best looking plants I've grown so far.

But I'm expecting things to go terribly any day now.
