Whoa whoa whoaaaaa. I stongly recommend that you dont add epsom salts to your soil. Sorry jbby81 but this is BAD advice. If you want to lock ur plant up so she has several more problems then go ahead and add them. There was a post about this recently.... it's not the miracle cure.

Is it week 7 from seed, flower or when u bought it as a clone??? u need to fill out the sticky at the top of plant probs with all relevant info
