Opnions?

In my opinion you would be surprised how much stretch you can get after sex shows. A little LST and you could do quite well with these plants…. Sometimes doing less will help I know you just want them to thrive and they will, I don’t like transplanting autos as it causes me too much stress, mephisto genetics are resilient and will bounce back in my experience. Maybe try and add some worm castings. But if you decide to restart I would suggest try using your final pot and just water around the seedling and just use more water as they get bigger. Good luck!
