Size

Try putting your light down to about 20 inches, after 55 days they should be much bigger and might be suffering from lack of light. Without a diary or much more info, there is little else that can be offered that would be accurate. I am also very surprised that it has not started flowering, being an auto means this should have started around week 4/28 days. Hope this helps,............ Organoman.

Plant on the left is double kush it’s just over 4 weeks old since broken soil

At first I had my light way to close so I raised it to the top of tent end it did stretch again The light is about 32 inches above the plant now

Something is definitely stunting their growth. Your light looks awfully high up, but I don't see any stretching.... Maybe try increasing the nitrogen a bit. You could always flip to 12/12 and let them bud. They should just about double in size from there.
