Advice Welcome - First Grow

Had to leave for a few days, so pictures aren't spread out well, mostly beginning of week and end of week. Upped the nutes a tiny bit to see the reaction of the plants. They took it well, and will be slowly ramping up as they get into flowering, which I'll be starting Week 4. Perhaps it's a mistake to flower so early, but I really don't want this grow to be very big, and they're already getting kinda big. --- One of the plants are unruly, really just growing however it feels like it, super dense and bushy. My other plant is a bit nicer to look at. I expect the nicer plant will have more easy to manage bud sites. --- Did some defoliation, just a teeny tiny trim. Generally just pulling leaves that never got light or which were already starting with wilt. Snipped a branch off of one of the plants because it was tiny and wouldn't be able to compete with the other stems. --- Finally got an AC, so temps are now completely dialed in. AC unit has terrible dehumidifier control, a static 8 minutes on 6 minutes off. During those 6 minutes, the humidity will just cozy right back to ambient. Will be getting a seperate dehumidifier to help. One of my biggest fears is developing some kind of mold or fungal infection.
