180g from 3 strains on 1/2 closet

This was a tough week. I was away from home for the entire week, so I couldn't adjust the light distance properly nor properly water them. A good friend of mine came mid week to give the feeding I had prepared, but the heat wave hitting the city + not having the house AC on made the temperature inside the tent increase much more than I would like, reaching an average of 32 C (90 F) during the day. The high temperatures and the very low distance to the lights made the plants to dry much faster than usual, so when I got back in the weekend they were suuuuper dry. ~~ Stretching I don't know exactly why, but CBD+ and MobyDick have stretched more than I was hoping for while GG #4 stayed where I thought. The real surprise was the CBD+, which had stretched much less in my previous grow. They have grown about 1.2 inches per day! -~~ Burning Although CBD+ and Moby Dick have stretched a lot and thus got super close to the lights (6 - 7"), they were looking super happy and had all leaves upwards. In the other hand, GG#4 was around 12" away from lights but presented some burnt leaves. She wasn't looking very happy at all. -~~ Adjustments after the week off I've defoliated them, removing dead and excess leaves, cut some lower branches that didn't stretched to make up to the canopy, and obviously adjusted the lights height. The problem is that now I'm literally without vertical space, so CBD+ and Moby Dick are about 12" away while GG#4 is about 16". If they continue to grow at this rate, I'll have a hard time
