Good luck. I just tested young bud from mine Stardawg and my mind is flying in sky. I think you put some wrong information. It seems that this is 2nd week on your photos, also I cant believe that you give each of em 1.5l of water everyday.
I would agree with Kali. Thats alot of water for a 1L pot. Cant believe how little yield you got bro.. Are you sure the LED was actually pulling out 600w? Maybe it was just to small a pot. But i hope it was good smoke! :)
