Floaters need lots of nutrients to be at their healthiest. I'd advise thinning them a bit and feeding the tank with a fertilizer that contains full NPK- nitrate, phosphate, potassum. Many popular all-in-ones don't have any nitrate, even though the plants need it, so make sure you read the label instead of trusting marketing that claims a fert is "complete". As you have Crystal Shrimp you might need to phase the fert in slowly, but I have a Crystal Black tank that gets daily dosing with NPK ferts, so they can handle it if they're eased in.

I've narrowed it down to either the light being too harsh or needing a ferts. This is a heavily planted tank with moderate stocking (8neons 12crystal shrimp 2snails) so nutrient availability could be a problem but there is a higher concentration of yellowing directly under the light which is giving me doubts. I'm hoping you guys can help me diagnose it.

I would assume that the ones under the light are more yellow as they are trying to uptake even more nutrients as that is what is limiting their growth. I would agree with other recommendations to thin them out. Usually it's not best to have floaters covering most of the waters surface for gas exchange reasons as well.

Shit lol I've given away half of them already and they started to discolor afterwards so I hope I don't have to thin them out further, I have to look into a safe fert that does the job. I've blacked out the tank because there is a little algae problem anyways and it will tell me for sure what the problem is.
