i use Top Max. you only want a couple of nutes like Root, Groom, Bloom, (unless you use tap water) Rain water is the best (N)
Root juice first then nothing for 3 weeks then (Remembering that Good soil you buy has 4 weeks foods for the plant) (Groom VEG) Then Bloom 3 weeks befor the end of Flowering
And the reason its so small is coz the amount of light your useing and the soil (cannabis needs soft soil the best thing to buy is soil with a little sand in as the roots can make there way though easy and the water doesnt hold) ((((GREAT FOR CFLS))))
What watt is the bulbs your usieng and dont listen to everyone who says put the Cfls Close put them about 5 inc away
really you need about 75watts + but tubes dont work very well sideways but they are better standing up coz it helps the plant to grow with it .Nice and tall
