Re: 4.week flower cheese strain coco grow nut burn?

I would back off to EC 1.4 or 700ppm on the .5 scale. Looks like over fert or potassium def. & Iron def. Keep giving them 5.8pH nutrient solution with about 10%-15% run off.

Coco likes to bind up cal-mag & potassium, so you will have to supplement cal-mag in coco..just FYI.
