Hi mate. Do you mean a defoliation?? If so, you could get various responses. Most guys wont stress them that far into flower. I usually defol for the 2nd time at about 3 weeks and leave it from there, just taking the odd leaf as required. For me if its in the way of light to the buds, and it wont tuck in, it gets picked out. Some strains have long internodal spaces so each leaf does a job, others need more attention. You gotta go by feel on this one mate! Good luck, they look great👍🏽
