FIMIN During Flower?

After the first week or two of flowering where the plant stretches in the "pre-flower" stage topping/fimming wont do you any good! At that point your plant doesn't focus in foliar growth but in flower production, and any kind of stress like that would be harmful to your plant! Also refrain from defoliating after that stage because the leaves are your plants' energy source! if they grow above bud sites the just tuck them underneath! Hope this helps! Good luck and happy growing :)

Agree that you should probably hold off on any more stress at this point. Let the plant focus its energy on bud production during this critical period of early flower. Best of luck keep up the great work

After 2 weeks of flower, the only thing I'll really do is very light defoliation. You don't want to stress them when they're trying to make you nice, fat flowers. You might have some luck if you're growing a satova, but I still wouldn't.
