I'm glad to have found this journal! I have a similar grow (2 x 45w inductions on two plants).
They do get a little warm in a small space, I moved my filter down to about a foot above the lamps (versus strapped to the ceiling). Seemed to kick the warm air out much better. The canopy temps went from an average high of 82ºF, down closer to 75ºF
As to training your bag seed, The attached pic is from thread by BigFatJ who did some cool mini-scrog stuff - Each plant has it's own screen attached. Apparently it's from an old post, but it was new to me
