Hey HC those plants are looking fine. If you are looking for nutes I use fox farms or you could try GHs 3 part they are really good nutes to use or just do a search and read up on all the nutes out there and pick the one thats easiest to use for you. How many watts of light are you using and what are the ppms and the ph numbers of your bubblers.:rasta::rastasmoke:imp:
