You have no choice but to completely cover the light leaks. Otherwise you are going to get hermies, slow ripening, and other problems.
Just keep an eye on your plants. If they get even more droopy edged, you really will want to re-pot. If they start showing weird splotches and burns, the soil chemistry is going to shit and you'll be flushing. Keep us updated. There's a drop-dead point like, yeah you AHVE to repot NOW but you aren't there or even close haha.
