Mainline, Bondage and Supercropping.
The size of your tent means you want to use every possible cm for leaf surface til you bloom and to build a strong stem structure to support the weight of the developing buds during flowering.
See pics below.
Use wire hangers stuck into the potting medium to hold down your main stems to spread the lady out nice and wide. Top or FIM as usual and you'll get a short stocky bushy mama that will build colas everywhere. Her growing tips will turn up toward the light within hours of tying her down. Before taking any clones, GENTLY "groom" the girl so she splays wider and wider by holding her branches out to the sides with the wire hangers until you get out to the container's edge.. If you split her at the trunk, don't worry. Just support her so the crack is in contact with the stem, and she'll heal up quickly. You'll be able to take like 16 clones just before flowering. Believe me, you'll have them! Go ahead and let them grow so they're substantial enough to build solid roots quickly.
Foliar feeding and misting should be done throughout veg. I do it. if you don't wanna, fine. I only use Thrive Alive and "stood-out" tap water.
At that point you can trim out under the canopy, (lollipopping) to clear out anything smaller than about two inches tall. Take the fan leaves out with the little "sprouts" but be judicious, some of the little ones under the canopy will yield enough smokeable bud to give you a few previews before main harvest. I love previews.
bushy and squat. that's what you want in small tent grows. Hell, bushy and squat is always what I want right before flowering in a tent. They'll stretch like mad and I don't want them growing into the light. 750W HPS BTW. yeah....
peas.
