First Hydro Grow - Ebb Flow

@PunkrockNoir, hmmmm doesn't say how much calcium is in the water

@Grower202085, https://ibb.co/82Zj8Sc 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.

@PunkrockNoir, Do you know the water quality ? Like how much calcium and trace elements are in your wat3r ? My water is 0.6 0.7 ec but I have high sodium so it'd classed as "bad water " I'm using rainwater right now but I'm finding it hard to dial in :( any tips ?
