So my plants are at week 10 of flowering. Is it ok...

You have a bunch of things going on here. Big change in the plant in just a week. First off I would back your light off a bit 15" seems very close. Go by what your manufacturer recommend for distances. Your bloom light puts out some infrared spectrum which can heat up your leaves surface temperature enough to cause some light burn which is what your dealing with. It is hard to tell but the light burn is causing a bit of premature browning of the white pistils on your buds and may be stunting their growth. https://www.blackdogled.com/lst I'm not sure of your nutrient routine but adding in some Cal/Mag into your mix will help your plants deal with light stress a little bit better. Looking at your bud development I would suggest using a PK 13/14 type product to add some growth and bulk to your buds over the next few weeks. As for the leaf removal your plant has nice open form to her I would just remove the leaves that are dried up the most as needed but try to leave as many on her as possible until your closer to harvest then gradually remove them.They will look worse for wear by the end of the grow. 👍

Yes, it's ok, only remove the leaves where it's needed to get to the lower buds. You should be ok after removing some of the fan leaves. Select the leaves that you want to remove, clean your scissors, and cut them. It shouldn't cause to much delay in the grow, the lower bud will get better light and will get more dense than before. -Some of your plants really need some calcium, a lot of nutrient burn on your leaf. Add some cheap calcium to the soil asap, or water with half strength nutrients. This can be caused by many reasons, overwatering, overfeeding, rootrot etc.
