answered grow question 5y ago
certainly check the ph to make sure but with the plant being so bushy it could be from not receiving enough light.

Newer growth is lighter in color and thicker than the other leaves. She was under my humidifier so maybe drinking too much? Dry organic amendments so no additives in water. Several other grows in same feed schedule and no issues

Should I do full flush til runoff is 300ppm?
So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it? Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow. Today 3L water, pH:6.2, runoff:0.6l, ppm:1450, Ph6.0

Underwatering Issue or something else?
I haven’t been tracking exactly how much I’ve been watering. I usually water until run off. I’ve had to water daily because the coco loco has been drying out quickly. Is the yellowing seen in photos from 4/28 due to underwatering? I’ve been pHing between 6.2-6.4
