intreasting, i too have a similiar problem, not as bad tho, My b.b. is kinda actin the same way but only on the top cola, i see my top cola lookin skimpy... and more lower buds look really nice and dense, im not sure why they do this, i raised my lights to see if it was some sort of burn byproduct. They just started to grow more not in bud production but hieght. im hoping they fill out like 4x5 said, but im only at like week 3 of flower. So im alittle behind, my buds look the same sizes not filled out as much. B.B. puts on alot of wieght int he last week or 2 i hear.
