Thanks for responding. They have been in the three gallon pots about 8-10 weeks. 4 weeks of 12-12 and 4-6 weeks before flipping (planted as clones).

You're way rootbound. Do what I instructed above. You want to try transplanting once every 4-6 weeks. Starting with 1 gallon pots and moving your way up.

If you're starting from rooted clones then you could just throw them into flowering as soon as they're done rooting. Put them in a 1-2 gallon pot and let them grow for the duration of their flowering period so long as you make sure to flush the pot every few weeks (3-4 weeks).
