hey Moses,just poppin in to say what up...I grow in a small space like you have going on,have you considered using t5 flouros,I use 3 4ft double tube t5 in a 4ft by 3ft by 7ft tall closet and the heat and stretching issues are not a prob,you can have light as close to 2or3 inches from the top of your plants,this minimizes stretching,I imagine any type of hps will be very hot in your limited space...I grow photo period strains as well as autos and have noticed that the auto leaves can look kinda funky at first and will change the more mature it gets,as far as nutes,I use veg nutes(grow) all the way through on autos but drop to 1/3 strength after they show buds,I will add bloom and some cal mag till they finish,you can grow autos under t5s all the way with good results but a 400 or better will def give you better results if you have the space and proper ventalation,they now have t-5vhp setups that are awesome also...I have a seperate flowering space where heat is a non issue,veg under t5s and bud under a 430 agro,stay with it bro and green mojo your way....peace ps spend the extra cash on a 400 or better,u wont regret it in the long run....jmo
