Great job recovering them, nicely done. They look a bit dark to me so I would lay off the Nitrogen a bit, but it could just be the lighting. I always use
BioBizz which just involved me feeding the plants fish mix until flower, should be the same one nute until flower deal with most organic lines. Not sure what system
foxfarm nutrients use, but just make sure you are not using flower nutes during veg, I knew someone who did this and wasted a whole bottle. Their leaves were always really dark and I could never understand why.
