Any idea why they're yellowing? 4x4 Rockwool and still top feeding. One has red dots?

I had them 8-12" but I now moved them to 12-18". Hopefully that's it. The pic here is same system with different things happening. Meaning Nutes and PH in Rockwool.

Can't really tell because the pics aren't focused. But from what I CAN see I see burnt tips. How close is your light?
Thank you. Sometimes I'm not the sharpest tool in the shed and as I look at specs for light distance, says 12-18".

Don't worry the only reason people can help you solve your issue is by going through it you feel me. My lights are so strong and the manufacturer recommends 24inches..but I had to put them to 36inches. it'll take a week to bounce back. Less light is optimal...because if the raise in light height isnt enough it will stay stressed and prolong the bounce back.

I'll keep an eye on it the next cpl days. So far new growth isn't effected. Thanks again.
