Thank you @owasco!
I think the previous yield was low for a combination of reasons.
Early in vegetation I made a terrible mistake of planting three cannabis plants per container, restricting the root systems and plant spacing. I had to perform an emergency transplanting and give them all their own containers.
I also overfed them and burned some of the critical foliage which supports bud growth later on.
Aside from that I was going through a relationship breakup, and this isn't something I deal with very well emotionally, so it was effecting the plants and my ability to give them the best care possible.
I still thought the buds looked big and expected a lot more.
I'm confident this current grow will be my best grow ever.
You love and nurture your plants so well, I can definitely understand how being in a less than optimal place yourself would affect their development.
Growing for a high yield seems to require an awful lot of attention! I know my garden could produce much more than it does if I were to give it all the care you give your lovies.
Good luck on the next batch! I haven't managed to get up there yet. Too much gets in the way. Hopefully things will settle down, before I have to be home tending my own crops.
