Not growing?!! Help w/ sour diesel

whats goin on. Ive had a great harvest so far. Started w/ 10 plants (7different kinds) and have gotten to my last plant which is sour diesel. It has been topped like crazy and has great potential. The problem is that its about 75 days into flowering and still looks immature w/ tons of pistils still on it. It has already started to yellow and looks like it just stopped growing. It still is suckin up water and nutes w/out a problem. Anyone have any suggestions? should i try somethin like superthrive? peace

when you say topped like crazy you mean before flowering right? If you top after you might stress the plant out or something. Without pics it's really hard to help.

The flowering time for sour diesel is 70-80 days. Should be done in 5 days time. As long as you give them a good flush, and they are still uptaking water then they're going to be fine.

yea, before flower. It has a main stem of only 8 inches then about 10 stems rise about 2 feet. It just really looks immature and the pistil arnt changin and it doesnt seem to be hurt by any nutes i give em. Ill just keep checkin it day to day.
