Transplant stunted auto?

Is the plant already showing pre flowers? (I can't make that out from the pictures you shared.) If so, flowering could start any minute. If not, flowering may not have been triggered yet. In both case, I would transplant her and give her the necessary tender loving care. Tender loving care also includes cleaning, tidying up and disinfecting the grow space. The ground surrounding the plants is quite messy. There are stains from previous feedings that may contain and/or are attracting unwanted pests and diseases. All in all, that's not helping the plants any. Definitive tips: Clean the grow area! While the tent is drying from disinfection you can use that time to transplant :) Hope it works out in the end.

depends on what you are expecting from this auto plant. if you want it to be big and perfect....its probably too late. take it out. but if you want it to recover and maybe still harvest the buds though its size wont even get near its ful potential.... keep it. but keep in mind: automatics are fast and chances are high that if it goes into flowering with this high level of stress then nanas may appear.

Be happy it didn't go into flower early -- and may not know if it is currently in flower as it takes 7-10 days to see that development after it starts. You only know in a belated way when its in flower. The pot may limit size of your plant too. So, potting up would be wise sooner than later. As long as you don't molest the rootball or break/rip a bunch of roots, you should not experience all this "shock" i hear about from transplants. In 6 years i've yet to see shock from potting up. For every plant i've grown, i've done 2 transplants for vast majority. Gotta be 300-400 tranplants at this point and zero shock. I saw a plant shocked one time. it was a dumpster fire clone swap plant with bugs chewing up its roots. I removed the substrate from the root mass by dunking it in a bucket of water and running water over it repeatedly to remove all the 'dirt' they called a medium. That plant took a week before it started growing again in a new larva-free substrate. That was the one time i saw a plant 'shocked' and the reason was quite extreme... not from potting up. Still zero for three-hundred on that front, conservatively, lol. zero for three-hundred is not the odds you play at vegas.
