Seedlings need help bad

[Dieseldually]

HI these seedlings sprouted about 5 days ago and aren't looking right. At first I thought over watering and waited 24 hours and the rapid rooters were completely dried out. I PhD my hydroton to 6 and accidentally adjusted my res water to 4.5 which is low, could this be the issue? Using a large 200 q CFL temp 20 c humidity 50 lights 20/4 any help would be greatly appreciated thank you

just keep your pH between 5.5-6.5 and keep the cubes moist with the solution if the res isn't keeping them moist with the hydrotron, they should be fine.

Are you running just water or do you have nutrients in your res?

Hey thanks for the reply they aren't exactly in a res they are just in a large Tupperware in net cups and I'm pouring water over. First I was using bottled water at Ph 7 then using nutes at literally a few drops for a galling ppm is 300 using Flora nova nutes

I'm growing Vert so I'm doing it this way until I get a bit more growth for a MH. My runoff was 6.6 if that matters. Pulled a rapid rooter quick and roots were brownish, is this nute Def and over watering?

If the roots are brownish, you might have rot from over watering. Flora micro can stain roots a little, but you're using so little I doubt that's it.

I'm not familiar with rapid rooters, but I know jiffy plugs hold moisture pretty well, and so does rockwool especially if the plastic wrap is left on. The rapid rooters might be staying too moist and not drying out, which wouldn't have alleviated itself just by drying out once and then being rewatered. IF you have rot, you could use a mix of hydrogen peroxide (medical grade) and water when watering (you'll have to research ratios, I haven't used it, just read about it) to get rid of the damaging bacteria. The roots will have to do some repair and regenerate so it wont happen over night. Your setup looks great otherwise, so I think you might just be killing them with love. I'd try watering less at a time and let the cubes dry out a little more often if possible.

That should have said flora nova, not micro...but I can't edit yet.
