Hello fellow grower :wave: 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!
