Hi
@DizzusBoy ! Because you did remove too many fan-leaves on the plants, they're building a lot of tiny leaves onto the buds, in order to grab energy from your light. Now if you want to know when to harvest, you should use a magnifier or microscope and have a look at the trichomes onto the buds. Clear and skinny trichomes --> too soon, milky and fat trichomes --> best time to harvest, amber trichomes --> too late, THC is degrading. Hope this helps, keep us up-to-date and happy growing!
