Hey guys, nice looking plants, some strains swell earlier than others, they dont look swollen yet so problems aside they will probably push out another flush of new pistils adding more yeild to your bud.
If there were problems, recently i overferted and buds stopped dead, then this could be why growth has dropped off but i never really get early swelling when i get problems so i hesitate to add anything here.
I use 2 x 250 watt cfl's for flowering, one red and one blue and run a packed flowering room, when the light penetration drops of so dose my bud size, probably got 15cm of good workable light before penetration is halfed by the canopy of leaves. I top em early, pinch em, lst em and flower them early, bigger plants equals bigger top buds to me but i need a quick turn around so i only veg for 3/4 weeks under 4 t5's.
I have a 125 watt cfl but that sucks!lol! Peace
