Just off the top of my head:
1. I wouldn't have stared them in peat pots, I'd have started them in larger, and more importantly, ph balanced containers
2. I wouldn't have almost killed them with my 400ppm tap water
3. I love the nute solution I'm using, and I have enough for several more harvests, so I'll likely keep that the same, but I wouldn't mind experimenting as my money allows.
4. I wouldn't veg as long, 2 months was plenty, and 3 made it so I had to trim them down a LOT to keep them the right size for my space, and I don't like cutting up the ladies! (until they are done!)
There are probably other things as well, but those are the big ones
And, here is a day 62 update!
