#1 is spreading out nicely under the ScrOG net, and #2 is not too far behind but much bushier. The color on #1 is still a bit light so I fed it a little extra this week. #2 is nice and dark green, but I did notice some rust-colored spots in the middle of the week and started adding some CalMag to feeding for both plants.
I watched a video where a guy had 4 plants of different heights. He raised the pots of the 3 smaller plants, each by different amount, to create a level canopy. That might help you if your 4th plant is smaller.
good luck with it all, I'm a noob so cannot offer more than 3rd hand advice and best wishes.
