I have 1 girl scout cookie that has a few leafs like this. I'm feeding it the same as the other GSC. Running about 1100-1200ppm and using calimag with r/o water. Ph is right about 5.8 -6.0. Temps have been in the high 70s with light and high 60s without. This is in 3 gallon smart pots using 2par coco perite medium.

This is off the lower part of the plant. I'm using 600w hps and it's about 1.5ft from the lamp with a fan blowing over the canopy.

First though is light burn/chemical burn. Are you spraying it with anything or letting water get on the plant?

I've narrowed it down to calimag deficiency and nitrogen, new growth was starting to get the claw. The leaves with holes were at the bottom.
