Help needed

The plant is in a sip , own soil about to flip was away for 4 days, nice growth but leaf color doesn’t look good? Need a good fix cause there’s 9-10 weeks ahead

More information on nutrients/watering, soil composition and better pictures and more of the plant will help also.
But first glance I would guess mag deficiency.

Cal mag foliar spray would be quickest fix. In hind sight I should have had this is stock myself as my led lights really ate MG. Your pic looks like classic examples in gwe and other sites.

My soul is a book to write about, mag was my thought, cause my soil , when I mixed the first bag of calcium had no magnesium, so I bought a new bag with magnesium and did some top dressing so it’s going to take a while before it gets to work

Might try a foliar spray of mag to speed it up if damage is still spreading.
Best of luck!
