How much longer for harvest?!

They look nearly ready so there's not much you can do, there wouldn't be much you can do anyway tbh. This is definitely from over feeding, this happened to me once and they're was nothing I could do except back of on the feed. check out my bigdevil on corona grow diary. Same thing I believe

First of all well done for growing such a beautiful plant shes close to finish for sure and thats why you are flushing her I assume ? If you are not flushing her she has a serious Nitrogren defiency and phosophorus but looking over the pictures and seeing the other bud that isnt as mature as the rest its compleatly upto you but why not do a selective harvest though it all depends on what your going for couch lock or clear head ? if you want clear head chop her now but if you want a balance between the both i would let her go one more week though this is you plant man you do what you want :)
