plants wont finish

Ok so ive been doing this for a while now and i always seem to have a harder time hitting my makes in the winter than the summer but this time its getting ridiculous. best i can remember i turned the lights back on nov 15 last year and now being the 2 of feb by my count thats 79 days in 12 12 for nirvana seeds ppp, which is supposed to be a fast to medium strain, is there anything i can do to seed this u, im mostly cloudy but no amber yet and i want 50 50. any help will be greatly appreciated

do you have any lights leeks? and it sounds like your close. well some pics would be good

How are your night temps? I am having the same trouble here. Have been growing AI that has been finishing in 45 days, I am now at 50 and the bud mass is not there. I had some nights at 57 deg I have now corrected that and do not allow temps below 65.

I have found that not watering for 1-2 weeks before harvest, and an 8 hr/day light regime works well. With the exception being total darkness for the last 3-4 days. Not watering allows the plant to use up all avail nutes, and the no lights trick the plants into producing thc as a last ditch effort to propagate. This has always worked for me.

i actually know all these things and have been working with my setu for a while so its really not my concern, im more like mr juatabud, my girls should b done and the mass should be more, all i can do is wait i guess

The most common reason for the flowering process to stall at the end is root binding. Carefully remove a plant from its pot and check the roots to see if they are circling repeatedly around the bottom corner of the pot.
