0/6/9 and getting the "claw"/rams horn?

hell yeah! glad to hear your plants are back.

I was on 0/6/9 per gallon. I read this grower say that the strongest he goes with h3ad rezipe is 0/5/7.5 with his prophets under a 600w. So i have been using 5/7.5 for about a week, the leaves have gotten a lighter green and the clawing is subsiding, although a couple of my larger plants are looking slightly too light green so i might go back to 6/9 for them.

How did you prepare your coco? Was it from bricks? Did you precharge it etc?
