First Grow - Jumping into the Deep End

I think everything is going well, but this is my first grow what do I know? The plants have very little internodal spacing. I mean like very little. They are squat little bushes with nodes stacked right on top of each other. Right now, most of the plants are still under 6 inches. However, they seem healthy, are growing daily, have healthy stems, and are eating and drinking. I have fimmed them all now, and are attempting to LST them. I also removed a few fan leaves to open up the middle a bit. I have raised daytime temps from around 73 to 76, with lows down to 68. I have lowered the humidity as well. I was trying to keep 60% humidity in the tent. However, I put a hygrometer under the leaves of one plant and saw 10-15% more humidity in the plant than the tent (from the buckets?). I lowered the humidity in the tent, and the plants started drinking/eating more right away. Also added a fan to move the air around in the tent more. Right now, the plan is to keep LST for another week, then switch to flower. Any suggestions or comments are welcome. Thanks for reading.
