if your girls are getting yellow tips and ur just watering,it might be the type of soil. what kind of soil
Nice Setup blackkmask. well done.. but if im going to do something like that I might as well buy a 400w HPS with a ballast , would come down cheaper.
and trailerparkkid, I'm using Miracle Grow Moisture Control potting mix... I know... not the best, could be the nutes in the soil doing this, or I may of had over watered them at the start... I will buy foxfarm soil for when I transplant . Hopefully the plants will last until then....
