First Grow Ever

Everything is going well in the tent. I had a sulphur issue that was cleared up with a little Epsom. I'm currently just watching the stem that I broke, it looked as though it had kind of bulged so, I put duct tape around it. Both Trans Siberian plants were defoliated because they just looked short and bushy, now the newer leaves can actually get some more light as the large fan leaves we're literally easch covering about 2-4 new braches/growth sites. I'm almost positive both of the Siberians have stared to flower but, I'm confused because the plants are still very short. Maybe I shouldn't have switched on the bloom light. I was just under the impression that autoflowers started to flower automatically and the more light the better... Who knows, this might even be a good thing. There's still ample space in the tent so I'm hoping the defoliation didnt stunt the growth and they fill it out the tent a bit more Slightly confused as to why my Trans Siberian has started to flower without branches Topped SP2+TS3 with F.
