Dear all, first time posting on this forum although I have been using it a lot to help with my first time grow. I am now at a stage where I need help!! I purchased fast and vast, and afghan kush ryder seeds grom Gorilla-Seeds and they also sent me 3 more random ones which i germinated a little over a month ago now. I have been doing the grow with an experienced horticulturalist but not with autoflowes and they insisted on transplanting them, first into 1L pots and then into the 5L pots they are in now. They have started to come into flower the last couple of days and I have a bit of a dillema.
The question I have is wether they should be potted on again, as the first roots are showing at the bottom of some of the pots (of the afghan kush ryder), or I should leave them in the 5L pots as I might lose more than I would gain from transplanting them. If the transplant is done well how much growing time would be lost? I feel I have already lost a lot of yield due to not having ideal conditions during the grow so this is important to save them!. Any help is appreciated. Also I wasnt exactly sure when to change their feed to flowering feed, I heard I should still be giving them nitrogen based until they have finished growing verticaly to maximise yield?
Here is a picture taken a few days ago before they started budding, they have got a bit bigger since then but just to get an idea of the setup. (P.S the big one in the corner isnt and autoflower and isnt mine, its going to be moved into the ground soon)

Info about the grow if anyone is interested!
I havent been able to give them the conditions I would have liked, during the seedling stage I think they did not get enough light and the afghan kush ryders grew very tall and leggy and needed propping up, I then had to relocate them outside for their 2/3rd week of growing after they were moved from 1L to 5L pots. They hardened off outdoors but I feel they lost out in size. I could then finally move them into a greenhouse which was not available before where they have been flourishing and really come along in the last week. If I could have got them in there a week earlier perhaps they would have grown better but as they are I'm pretty happy. Ill keep the forum updated with their progress from now on!! All help appreciated
