need help with indoor

Hey everyone people call me fmj. I have been growing for 6 years outdoor and have had 100% cloning sucess for 4 years. I live in maine and I'm trying to become a legal caregiver. I know I'm not perfect at what I do I still have much to learn. I started my first indoor grow op. Idk why I've been cloning for years and havnt even tried it but I simply didn't have the space I needed to do it. I have 2 closets I'm using one is for cloning and veg using floresents. And my bud closet uses 600w hps my closets are roughly 2feet by5feet. That's perfect for my veg and cloning but I'm thinking my hps bulb it too big maybe I should try 400watts? I have ventalation sucking the hott air out and another vent that brings in cool air keeping my closet at 80. I'm growing carthredge red,strawberry diesel skunk#1 and super silver haze. I noticed my plants are too tall for the bulb so the leaves are getting burt a lil and that upsets me so I have to tei them all down but once I do the budz explode so maybe I should do a scrog or sog what do you guys think. Ill post pics once I figure it out since I use my cell for everything. And the carthredge red ill post on it is a rare strain that I know too well haha.

You may want to try and LST your plants.

I think I will try that does make sence keep the plants lower with minimal stress. Much appreciated thanks man ill post a pic when I do it to my hash plants
