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).

They did great through vegetative growth and looked really healthy up until about two weeks into flower, although I did not get the additional growth spurt I usually get in that first two weeks of 12/12. Starting week 3 yellow leaves started showing up, has continued to get worse, yellow,curling, brown and grey leaf edges. Also,the overall color of the plants has turned to a bright neon like green.
