Hey everyone, looking for some input on some amnesia haze seedlings that are 2 1/2 wks in from sprouting. Sitting in FFOF, watering every 3 days or so depending on how thirsty they are. Under a 2ft/4bulb T5h.o. EnviroGro light. Lights are about 4 inches above the plants. Plants are about 2intall. Very very light rooting nutes twice now but mostly filtered water. Thanks for stopping and looking!

I can't see anything wrong with them. They're a little short, but I wouldn't change anything to try a fix them. It could just be how that strain grows.
