i know I barely have any space and 4 plants was a mistake lol but its my first time and I didn’t account for enough space, too late now and I’m going thru with it. Any future things I should worry about because Of this mistake? If you have any advice please hit me with it. I just wanted to show my progress as promised, any educating criticism is welcome. thank you all!

Looking great! Just continue to do LST to fill up the grow space and hopefully you won't run into height issues. Are you planning to add a trellis net?
