Welcome to OG!
Your plants are looking pretty good! Its normal to have plants from the same strain look like different plants, these are known as phenotypes. Most of our strains are hybrids so even with fem seeds, you will usually get more than just 1 phenotype from a pack of seeds. Totally normal.
For the tilting, like @legalcanada says, is totally normal and I also recommend to just rotate the pots a bit every day or two.
What soil are you using? The dark green is usually from a nitrogen abundance, this can happen with soil that already has a good amount of nutrients in it, like Fox Farm’s Ocean Forest Soil. The plants should grow out of it though, nothing to worry about.
Do you also have another light by chance? You don’t absolutely need it but usually, in order to properly light an area with quantum board led’s, you want to have around 30-35watts of QB led light per square foot of grow space if you want to get the most yield possible from your plants. A 3x3 tent = 9 square feet. So to hit 30watts per square foot you’d need 270+watts of quantum boards in there. I personally also have a 3x3 tent and I use 2 of the QB288 RSpec boards in order to do that. At the least two of the qb 100’s that you’re already using 1 of, would give you a much better ppfd spread. 4 of them dimmed a bit would be perfect for that tent.
