That shorter plant in the back left looks like a bit of a dark horse! Do you have anything you can rest her on to make her higher up? Some very healthy and clean looking plants here.
I look forward to watching you grow 4 or 5 next time. Very similar to my style. I enjoy the hand watering too!
It's so much easier doing 4 or 5, more soil, so feed them less. Less work. Plus each plant has more leaves and branches, so yields more, or as much as anyway. My advice, start 5, if 1 goes wrong, or you don't want to grow it out, 4 is then great, where as 3 is not ideal for 3x3 tents.
Keep it rolling!
