Curling down and neon green leaves.

I need a little help yall. Im fairly new to growing but ive not had this happen to any plant yet and ive grown quite a few in the little time ive been growing. None of my other plants are doing this and they are all in the same dirt. I haven't changed anything at all. The strain is critical Kush. I have a plant right beside it in the same room that looks great(a little strange looking but healthy haha). The critical Kush looks healthy for the most part but the leaves are a bit concerning since it is in flower and ive not had this issue before. I flushed it earlier just because. Any suggestions of what it could be? Ill post a pic of the plant thats in the same room too

Curling down can be overwatering. I've also had it happen when micros were mixed a bit too strong. Nutrient imbalances. Stress.

BTW, I'd suggest putting your plants under photography light for pics.

I don't see any neon green, but I see a shitload of blurple.
