If your problem is just low Ph then you do not need to flush the plants to correct the problem. When there is a problem you normally flush the medium to correct the problem. When the problem is only Ph miss balance you do not need to flush to correct the problem.
Zandor Reviewed by Zandor on . PH too low This morning, i notice that at least two plants had a coloration problem. No green in the center of the new bud. I checked PH, it was 4 ans EC 4 also ! I flushed the containers and i put new nutes. Do you think i should have give them just water with good PH? Or is it good now ? Fhydro Rating: 5
