First Ever Grow! Error 404 Autoflowers!

June 14th not a ton happened, I believe I watered them (It seems I am having to water every second day now as they start to get bigger) June 15th - still just growing away. I went out and got some different ducting so I could pull air from outside better with the ac infinity inline fan. I also received some insulated ducting from Amazon that is a hell of a lot better then the standard stuff I am using. I also grabbed a new 9 inch fan (still deciding the best place to place it, for now it is beside the door). I grabbed a larger oscillating fan aswell to keep air moving around. June 16th - decided I would do some lst and then I gave them some water. I have been feeding nutrients every second day. I have also on every 3rd watering been doing just ph’d water. The humidity seems to drop quite a bit within 10-20 seconds of the door being open hence the lower reading. I am sitting roughly at 45-55 depending on time of day. As for temperatures I’m still struggling to keep it down during the warm days and it seems the highest I am getting is around 29 since switching the lights off from 11am - 5pm June 17th - the girls seemed to have perked back up after yesterday’s lst. Not much new today just some growth! June 18th - Unfortunately I forgot to take pictures today. But not to much difference. I did feed the girls with some nutrient water today. June 19th - I again forgot to take pictures. They are just growing away and doing there thing. I did check for growth from the topped portion on the bigger plant, no growth from one of the 2 tops. So I indeed cut it to low… I won’t be doing that again haha. June 20th - finally grabbed something to deal with the heat since it is getting hotter everyday. I picked up a 10,000 btu air conditioner. I have it set at 23 degrees. I also moved the plants around and re-arranged some stuff. I took the inline fan that was taking air out and instead the ac output is going to there. I ended up having to make the vent into a 6inch vent on the trailer. Temps stay around 23 now. Humidity is still 45-55 depending on time of day.
