3 months is a really long time to veg. Everything looks like you're on the right track, you're just going to have to stay patient. The 400-watter is just fine for what you're doing...no need to increase. What strain are you growing? Some just aren't very good producers no matter what you do, and some just take their sweet time. I think if you stick it out another 3 weeks you'll be rewarded for your effort.
I like your idea of using a 32 gal garbage can for a container. Nice way to avoid getting rootbound, and gives the roots plenty of room to grow. Enjoy!!
