Looking pretty good!. I would definitely wait to flower on the venus OG's and probably the one in the terra cotta pot too if you are looking for 1.5. On the bigger girls, I would say that 1.5 is a very realistic target. Definitely don't top the plants and let them grow out like a christmas tree since you are going to have more height to work with than width. I strongly encourage around the 4th or 5th week of flower to stake these ladies so they dont snap over from weight. Or possibly excess heat since it is a small room and could possibly could forget to open up the door.
Lastly, since terra cotta pots dry out faster than the plastic ones, you may need to water that plant slightly more. Not saying that it is looking for water by any means but just some extra facts that could become useful later on. Congrats on the rejuvenation man!
