I say it comes down to the individual plant on recovery time, some don't mind and can take a full leaf strip but others will wilt at the mere thought of loosing a few leaves. Most of the time they are OK with it by just take small few at a time to be safe... now if we was talking photos you could be a bit more adventurous on the leaf strip.
I'm forever removing leave's during flower, especially if they are blocking a bud sites
what foliar spray do you use... I use Optic Foliar and can't live with out it, noticeably speeds up all recovery and growth... I have seen an acceleration in auto's when used on them, mine always got that bit more bushy.
