Fastbuds LSDx2, Six Shooter & Cr. Meth

This is my first grow with autos. I have had many successful grows so far with photoperiodic strains but I wanted to try the genetics from @fastbuds so I have 2 LSD-25 seeds, 1 Crystal Meth and one Six Shooter. The plan is to grow them 24/24 under low wattage LED bulbs in a closet until they start flowering, then they will go in the tent where I have a 140W (true) LED and a 250W HID light. I'm planing to use LST technique and I have a ScrOG net in the tent but I might run out of space since the tent is only 0.76 m2. I would also defoliate but I was reading that it might stunt growth in autos. Does anyone have to say anything about that? Also, something that I have encountered for the first time after many many seeds, the Six Shooter seems to be a Frankenstein! You can clearly see that there are 2 stems coming out of the seed! Has anyone seen anything like that before? Cheers guys Day 2. Seedlings are 4 cm tall, I started blowing them with a fan to strengthen the stems. I wonder where the true leaves are on LSD1 :) Day 7. Everything is ok. LSD 1 plant was taking too long to show the first set of true leaves it doesn't look too good, so I decided to pop another LSD seed. LSD 2 plant needed some extra support.
