Hey everyone first time trying dwc!!
Set up 4x4 tent, HLG550, water temp 70 degrees, seeds started in rock wool 2 weeks ago I am using GH flora at quarter strength ph 5.8.
At this point roots have shown from net pots. Today i noticed seedling slightly yellow. I just want to get ahead of any problems.
Question am I I doing something wrong or just being paranoid

No nutes RO water or day old tap water. Ph 5.8. Keep it like that till a week or so maybe till like pic 1 then give it 1/4 strength ph 5.7 if you want or 5.8. Ph will climb faster with no nutes so adjust if it goes above 6.8. That can take a day or so. After that usually veg will only need 1/4 strength of nutes maybe adjust more to the 1/3 ratio of nutes for flower. Haven’t needed to go up to half strength of 2 top of the line nutrients so far.
