whats your medium...
whats your ph going in and coming out.....
whats your feed and water schedule...
how close is light...
how old is she


looks like bad ph
light looks low... or you have high humidity.....curling upward leaves...im sure they feel rigid...should be soft

Could be spider mites

I had a plant outside, it looked that way through harvest. I think it could be a defect.

Thanks for the reply!

I think my ph was a little too high. I just recently started adjusting ph accordingly. The other thing I thought it might be is that the humidity was actually incredibly low- so the grow room was pretty hot but also very very dry.

Plant is about a month old. And now has two 300w leds about 18 inches above it. The first four weeks though it only had some CFLs

PH consistency will do wonders I'm dealing with low humidity and no spots my plants, didn't like being misted then they did spot, but not bad. I didn't try again.

Uhm,may i play the "Thrip" card here? it kinda looks like it just from glancing at a couple pics on google...Then again Green my RH was shite for ages remember? i didn't get a single spot!!Agree with the cupping tho,had that for 10 days...Check for pests,thrips or mites will look like that...Jewelers loop or at least 20x-40x microscopic lens to see the Thrips...
