If that were my tent, I would also clip those fan leaves on the tall plant that are growing over the shorter plant. I had that situation during my first grow, and ended up having to buy a cob to hang lower and dorectly above the smaller plant a small the larger plant was still shadowing her from the overhead light. I would also try to train the branches away from the middle of the tray to give the smaller plants as much light and room as possible. They can be monster bud producers if they don't get overshadowed! Pardon the pun!
