So I have a plant in 2 cubes on on top of the other and the PH was 6.5 way too high for my liking and I also an switching to flower to I mixed up 3 gallons of nutes and ph'ed it and just threw the plant in the 5 gal bucket with the nutes to saturate the cube and flush it and stabalize the ph while feeding it at the same time is this okay or do you think it will hurt the plant? I am only going to let the cube soak for about 10 min then measure the run off to make sure the PH changed inside the cube

Answered my own question by doing it. After soaking in 5.5 PH 1300 PPM then taking it out and measuring run off the PH was 6.0 and PPM were 700. Soaking rockwool doesn't do shit you have to pour over the top and completely flush the thing. NOW I KNOW :D YAY!!!!! Had to pour 2 1/2 gallons through the thing before the PH went down to 5.0 and PPM went back up

You're not understanding. The plant has been in the rockwool for a month and the PH shifted so I had to flush the cube with gallons of nutes to get the PH and PPM stable again
