also looks like you are locking out calcium and maybe magnesium. Ca can only be absorbed with a PH of 6.4 or higher in soil.

Yes I'm following the instruction on the back 2-3 tsp per gallon of water. I try to ph my water around 6.2

not 6.2. It needs to be 6.4, 6.5 is perfect and allows a perfect nutrient uptake. 6.2 can lockout nutrients. View attachment 2489393

See how with 6.2 you are getting little to no calcium magnesium and phosphorus.

yes i do thanks you very much from this.
