Okay guys, any help would be awesome.. i am using 1.25 teaspns of steath hydro nutes, which is not strong, but not normal strength. PH is 5.7. it has been about a week since i flushed.. I just added more H202 about two days ago and then started noticing the leaves yellowing.. any help would be greatly appreciated..
Im not giving em any grow nutes.. the Stealth hydro nutes say not to mix their nutes. i think it might be cause i gave em too much H202. they were at 3% from the last flush, the i stupidly gave em another 3% the day before this started happening.. but i realized that since the plants had already used about a gallon than now the concentration is a lot higher
I doubt it's from the H2O2. I overdosed my tank a few times by mistake(stoned) and had no ill effects. I would have to agree with lt. shiny sides. Less Nitrogen in Bloom nutes = yellow leaves. You're about 3-4 weeks in 12/12 right?
possibly also a calcium/magnesium def.
Hydro plants tend to get a lttile mag def. when they get into heavy flowering. Cal-mag <--- also contains nitrogen. Helps sustain through flowering
Just make sure it's not due to pH fluctuation.
You don;'t need any nitrogen nutes now, this far into VEG.
You used too much peroxide, too often, and just need to drain some water out, a couple of gallons, and replace it and wait.
