I have two seedlings that seem to be growing very slowly. The first sprouted 15 days ago, the second followed behind her at 12 days ago.
Live soil , Gaia green dry amendments , no top feedings.
lights 24-0 ,led Hgl at 36”
Temp max 68-80 day through night , stays solid around 70-80 during the day.
RH 39-57 max swings , stays solid around 40- 55
I’m thinking maybe the temps are a little cold / humidity is a little low.
