Seedling stopped growing Seedling 6/6 did not fully open its cotys and started to develop these small leaves. But then didn’t grow any further. The root is about 3.5” long and still white, but worrries because the plant is not growing that it may rot? Should I remove it from the grow? Should I leave it?

PH problems (DWC)I'm using 5% acetic acid (vinegar) to lower the pH but with 6 hours it's always back up to the original pH. A similar bucket with no aeration remains stable. Is it because I'm using a weak acid? Is there any way to buffer the solution to keep it in the desirable range?

Do you poke holes in ur seedling dome cups?When using plastic cups to dome seedlings (never have so just curious) do you poke holes in the cup for ventilation? I’m aware the point is to help increase humidity during early stages which I’d like, but do they need vent holes?
