Your plant looks good man. My only suggestion is I would try and put the thermometer inside the grow area. This way you can monitor the environment that's directly around the growing plants. I'm sure the temp/humidity are different on the outside than the inside of the tent.
maybe you can just list everything out so we can break it down with you. what kind of dirt? what kind of ventilation, etc?? looks good dude. here's a pic from my last grow that ended in june.
