400 watt hps full closet grow!!! :)

Hey guys, I just started up my little closet grow the other day, threw these 3 little clones (super glue og, gorilla glue, and master kush) I've got them in soil FFOF. Just gonna run them under HPS the whole grow, the plant tops are about 2 - 3' from the light. and I've got the fox farms flower nutes big bloom and tiger for when I flower them... the temps stay around 70 - 80 and I run an 18/6 schedule .. they've been doing pretty good, I'm getting a PH meter soon be cute I've been watering with tap so hopefully my tap is close to 7. Well see soon! Anyways. I was planning on only vegging for a month or so considering I only have about 5 feet height wise I can grow to. Would it be better to top them because of the height issue? Let me know how you guys like it or if you have any constructive criticism or questions feel free!!!

Red light(2700k) encourage distant internodel growth

vegging under some 6500k will allow the plant to grow correctly

rather then the stretched out shit you will have come harvest

then you say you are growing in a confined space

please make up ur mind

good luck
