I like the fast growth. I don't know if it's because of it being automatic or if it's a good strain. I have transplanted to the first pot and watered a bit. I also added a bit of sugar to promote bacterial and mycorrhizae growth...if there is any, to begin with.
You need to up the dossage on your nutes bro. Yellow leaves mean you don't have enough nutrients in the soil. Your plant looks ok for the size light you have. I wouldn't give up but maybe try an LED light instead. Good luck fam👍🏾
