Fastbuds LSDx2, Six Shooter & Cr. Meth

Day 8. Plant LSD 1 has the most growth so far, every other plant looks ok so far, except LSD 2, the one that sprouted almost without true leaves. Its growth is definitely stunned and it almost looks like it's sick. This is not going into the flowering tent and it's good that I have germinated another LSD seed (LSD 3) because it already looks really healthy. I might just leave the sick LSD 2 on the balcony and see what happens. Day 14. Transplanted all healthy plants to 16 liter smartpots. Started feeding them Advanced Nutrients Micro, Grow & Bloom at half strength + Voodoo Juice. Sick LSD plant will remain an experiment, let's see what happens. I could notice that Six Shooter was a bit stunned, probably because I pulled the 2nd stem off, but now it's growing again and it looks overall healthy. They re going to stay in the closet with the LED bulbs for another week or so and then they will go into the flowering tent. I'm going to start training them but I still can't decide if it's a good idea to top them or not. I have been growing photoperiodic plants for a couple of years now and I was always topping them but it's a widespread opinion that autoflowers are better not topped. Any advice is more than welcome.
