devil's advocate... the other solutions are more likely
Was this a problem from seedling? i've seen very similar growth that had nothing to do with a ph imbalance nor nutrients. it was afucked up genetically defective plant from seedling stage and never grew out of it... there may be pictures of it in my LA peyote kush diary.
it was blotchy, wrinkly, and just weird in general all over. some plants are defective... if it's been acting like this from seedling stage, it may just be a retard.
