First run of autoflowers 1/2

As we start 3rd week of flower, they started to show some pistils and the sex of the plant became apparent at this point. However, the plants still looked somewhat small for this stage. I am almost wondering at this point if I did anything wrong. As I haven't prune, top or trim any of the plants so far and they seems to grow not as fast or as tall as I would like to. This plants did grow bigger than last week, but somehow, I may have expected more. So far, still sticking to the same routine as the beginning, nute water in the morning everyday, One day it was pretty warm so I figured I would give more water to the thirsty plants, turns out that wasn't as good of an idea as previously thought. The next day, the tent had humidity built up on its walls. So, I turned the dehumidifier on to suck all that moisture, I had it on for about 2 half days. Between the fans from the tent, the networking equipment, the computers and servers running in my basement; I thought I didn't really need that extra noise when we're alseep.
