Indoors and when to flower, also Nutes

i have my plants in my room growing under my tv and it is a short tv stand only maybe 2 ft tall so i cant let them get to high so would it be ok when they are at the hight i want to change the light from 24/24 to 12/12? also what are some links or pictures of the nutrient bottles you guys have so i can just go into the store and buy it and how much do they cost? thanks

 

After a light change plants will continue to grow in height for about a week or two depending on the strain. There shouldn't be any problems switching the light over when you feel redy though, I believe plants can veg for about 1 week before being switched to 12/12's. As far as nutes go, I grow Hydro and I use BC products for my entire cycle, coupled with Sugar Dady, Tiger Bloom, and some Magi-Cal.
