flowering nutes?????

ive got 12 plants that are around 1' tall and just about to start flowering. my Q is what should i use to start the flowering and how much. ive got them in a 20"x16"x12" (LxWxH) plastic box with plenty of drain holes. im useing prosoil/wormcastings (50/50). ive got 10 4' floros but have room for 36 4' lights in a 4'6"x4'6"x2'6" (LxHxW) cabnet with CO2. the temp stays from 75-84 humidy around 40%. the ferts i have are 10/52/10, 38/10/10, superthrive, maxicrop liquified seaweed.i use wormcasting tea and the 38/10/10 mixed really weak for folar feeding once a week. i spray the leaves with reg water a few hours before the lights come on. i just got the seaweed and superthrive.
i want these plants to be done flowering by 3'6". they are bag seeds so i dont know the strain. ill post a few pics. im not sure how strong or how often i should use fert. in flowering with what ive got. i know 10/52/10 is kinda strong but its all i got. i live way the hell out in the sticks and im trying to grow as cheap as i can, this time. this is more of a learning grow more than anything.

to be honest its alot of stuff you can use, I myself im currently using the General Hydroponics Floranova Series,with all the additives. Now many here use Advanced Nutrients seeing how they are geared for cannabis and all,but from the looks of things you did very well,so im sure anything you go with will do. IMO what ever you use, try to go with their whole line,dont mix and match(though you can) i just think that same products work better with their own. well just do a Goggle search for Flower nutrients for cannabis and form your own opinion. hope this helps.

ONE!
