Brown spots

she looks hungry and thirsty. feed and wayer her well, she is in flower strech, most important part, needs max food at that time, definetly not enough

Hi ! You‘re that she has enough water ?

Likely Potassium deficient

Check the ph , it might be a bit low.

Hmm looks to me like an overfeed though I could be wrong and is just my opinion but best of luck anyway give her a flush and then look again in few days :)
