depends. can't see with pictures povided. will burn buds -- singed pistils look a little yellowish, for example. leaves can get interveinal dead spots. the plant might droop for many hours at end of day. sometimes light damage takes a week or two to really see it. i bleached the tops of a few colas in my last grow. shit happens. "HST" is a way to go.. they call it "supercropping" in this case. all you do is pick a point to slightly snap the stem. it bends horizontally and in a few days will be healed stronger than before. in fact, at that point you want to secure it from growing vertically, because it will try. the tip will turn upward, but better to tie it down or secure in some way so it doesn't stretch to close to the light, again. just grab in hand and push thumb forward till it partially snaps. make sure it's own weight isn't too much for it the first couple days after. LEaves may droop initially but not always.
