Not entirely sure what my issue is wether or not its iron or magnesium, OR neither and something else entirely. Its only affecting new growth at the top and on only on my fastest growing/hungriest plants.
PH is 5.7
Im growing hydro with the GH Trio and CalMag.

Currently they are in 5 gal buckets with a 1 inch gap between plastic net.
4ml a gal of micro, and bloom with 5ml a gal of grow and 4ml a gal of calmag
Any help is much appreciated!

That's from excess potassium, and the tip burn indicates overfeeding also, I'd cut your feed rate in half. And if you're in rockwool I'd give it a flush.

Wow excess! okay also im in hydroton. I appreciate the speedy response.

So dropping feed to 2ml micro/bloom/calmag a gal and 2.5ml grow a gal should be sufficient?
I also forgot to add that these are GDP from ilgm if that information helps any.
First time grower having fun learning how bad i am at this lol
These are nothing like reaper peppers!
