Dry, yellow, brown, curling leaves

Almost looks like she has "caught" powdery mildew from the tomatoe plants next to her.

Sadly gotta say that doesnt look too good bro, have you checked your plants for diseases? Looks like your plant may have some kind of pest, leaf miners/thripse/spider mites or maybe even a virus or fungal infection... Im not 100% sure though, you should check the underside of the leaves with a magnifyer and maybe wait for some other growers to give an answer.

could be a ph probelm buddy but certainly looks like shes not getting enough cal mag plus other nutrients. id say your missing the whole NPK here buddy best of luck anyway
