Hello fellow grower 👋 Nice start you've got there! PH 7.0 is a bit too high for iron to absorb properly. Looks to me you have a small iron deficiency going on. Adjusting PH to 6.5 should be the first measure to take and if that does not help, most of the cal-mag products contain iron in them. I hope it helps your grow. Best of luck and happy growing!

I'm not a pro so I'm just guessing but it looks like a light magnesium deficient. My pH is at 7 too in soil it should be alright.
