hello, do you remove big fan leaves and all the lower growth at day 21 flowering?
Week 8
Techniques. Defoliation

I've seen a few of the seed companies defoliate at the start of the final two weeks.
This to allow as much lights on the buds in the final bulking up phase.

Personally I wouldn't defoliate anything servicing primo bud sites and stick to leaf tucking whenever possible.
Those big healthy fan leaves, they are the ones that really fuel that meristem/node and its flowers.

Concerning light distance ... I always thought you have to end at Wattage/10 cm for HID. So 60 cm tops - at the end of bloom - for
a 600W HID.

i would always take that leaves away that block the light to the buds. and if you have an humidity problem, to get qa better airflow. and in the end of the grow ( last week) to "concentrate" the power into the buds. and tucking away tiny leaves and flowers in the bottom. If you take to much/ in altes stage, the plant tries to reproduce the leaves and take longer to flower. Its always a question of how much and when

I do my final defoliation at the end of week 2 or 3 in flower, but I make sure it’s the last time to do it. After that, they are on their own. To much stress after that point can lead to stunted growth and reduced yields. I honestly believe the yield you get from defoliation at the 2 or 3 week mark is noticeable. Let those buds get some light and air and they’ll return the favor!

cut the lower growth to promote more energy and production into the top of the plant as for defoliation some plants like it some don’t, it’s ok to remove the lower yellow ones like in the pic

I've done both leave them and remove them. Yield wise I dont see a difference, but defoliation makes them take longer.
