You are thinking of t-8 or t-12 they are not good for long term veggingfirst picture same as as his 20 days old and topped. 2nd picture is the same plants today at 34 days. im sure the tubes are nice but not for full veg without some extra lighting. i thought people just use them to start seeds/clones for a couple weeks till they can handle more light. maybe im just to stoned tired and rambling lol
They look healthy but if you fed them more you would be getting much faster growth. The problem when you were feeding them was more than likely you not pHing the mix before giving it to the plants.Every time I feed them more it just seems to mess them up. The medium I use is very rich and black, so I figured they didn't need it. I thought my plants look pretty healthy. I just took a lot of clones off them so they look a bit sparse, but still pretty good. The smalles one was stunted to begin with. My cousin gave me these and he's so sloppy I am surprised the other 2 were healthy.
