Hello,
It looks like the beginning of the need for a calmag supplement...the striping on the leaves always makes me think of magnesium deficiency, it usually has that interveinal coloring.
I used to think i never needed a calmag supplement because I used tap water and it's already in there...but once i started using it in my lineup things were much better.
Good luck with the grow ✌️
