What's wrong with her leaves? I've got sf4000 @ half power 37" away, happy frog Jumpstart, ocean farms soil, 60% humidity, 77 -82° temp

I don't see anything wrong with any of the plants. They all look healthy.

I got a few clones from a friend and find out it was the biggest mistake I made. They ended up having spider mites. Check the backside of the leaf. My guess it’s a nasty little critter

Have you looked under the leaves for some sort of pest?

This is my first grow, she's a blueberry big devil
