GSC White Label Beginner Grow

It's been a long couple of weeks but back to business. Had my nans plant in my tent with Mez unfortunately, hers contracted spider mite. As soon as it was spotted, I took the plant out and sprayed it heavy with spider mite spray and now her plant lives outside in the garden. I took both of my plants out and gave the tent a good clean down, and to take precaution I sprayed both of my plants down before the lights went out. At this time there were no spider mites on any of my plants! After a week or so I still didn't have any. About twelve days later, I unfortunately spotted spider mite on one of my plants. At this point I have been defoliating and lots of LST still. It was important for me to have the bottom of the plant to be clear so it can get good airflow. As of speaking right now, I have successfully gotten rid of the spider mite to the best of my knowledge. I only found activity on one single leaf, so I took it off and gave both plants another spray. Other than that, things have been great. It's summer time here and I'm having issues with getting cool air into the attic. I have a big fan but that doesn't really help too much. Worried about getting bud rot in the future when I switch to flower as I don't have any fresh air getting in there, but saying that my nan has been growing in there for years and has not had any issues. I've learn a lot so far. With my plants I'm being more hands on with one and less hands off with the other. I also changed my light as I wasn't happy with how they were growing. The light I was using pointed the light down instead of around the whole tent. This made shoots in th center of the tent grow quicker than the other side's and I had to keep turning them around. Now I've changed the light, it seems to be growing more evenly and I think the light I was using before hindered the growth speed and quality, but they still look great.
