Has anyone experienced this before. I know it might be strain related, but I swear that they all (7 plants) started out gang busters in the first 4 weeks of flower. Now at the end of week 5 going into week 6 they seem to have slowed down at the top of all the plants. The buds below seem to be filling out better and getting frosty. The top buds appear to be growing up with more leaves and not getting fatter. The strains are snow white, blue mystic, strawberry bubba kush and alien dawg. The alien dawg is doing this the worst of all the strains. I may be getting impatient with them, but they appear to slow down. Thanks for any input and thoughts on the matter. Nothing has changed for their envirnoment, but I have added grow big and beastie bloomz to their weekly feeding per the fox farm schedule.
