Do u lower N going into flower first 2 weeks? What's ph of ur solution ? Do u add h202 in res? Do u use bloom boosters?( not really a need if u get nutes dailed in )does ur medium drain well?whats ph of run off compared to intake ph/ ppm? Temp, Rh lights on n off?

could be alot of things small grow area, not enough lighting/too big of area, not enough co2 getting to buds, not properly feed, genetics of the strains your growing. I'd say defs or not properly feed though maybe a ph def. im not a super grower or have alot of experience but have read alot and id say those are your problems

Also pot size we need more details not just I got it down but it don't work.
