Need to look at the other end of her to decide this. If that is a regular size solo cup only about 2/3 filled judging by the top growth I'd say she is ready. Depending on your final pot size I wouldn't be moving to a 3 gallon so soon. But I have no idea what your final pot size is.
I do this-about 3/4 solo cup but wider to half gal to 5-7 gal.
Thanks for the feedback!
Oh and should i start my ff trio half strength after transplant? its in ffof soil.
Just transplanted her to 1 gal. like suggested.
you can start to feed her but i'd start with 1/4 strength. i use ocean forest, usually veg for a month and i don't feed them until flowering cycle. ffof is pretty hot usually enough nutes to get through veg
So far even though its early ffof seems to be doing well. Ill wait another week and then do 1/4 strength and test. Ill post a photo of her in her new home tonight when the lights come on. Thanks for the help!
