so this is the second run that this happens exactly the same at around week 4 of flowering. everything was fine before hand but now I get these issues. ive had tones of other runs and not ran into problems this bad. I'm feeding jacks part A and B with added silica every other watering. I do a feed feed water schedule in promix HP. PH is usually between 6 and 6.1 .

any suggestions on what's going on and how to remedy it??
