This week buds are getting bigger.
Plants are pretty close to the lamp but still feel ok. I keep LST them but now i'm gonna have to bend them horizontally or even backwards. The real issue is that the huge amount of leaves turns everything into a mess. Now it is too dangerous to defoliate them so I should not expect to get something good from lower buds but hopefully higher ones would get enough light.
Next grow I would remember to totally defoliate plants after switching to 12/12 if I decide to grow two plants in my box another time.
