Welcome! People here will help you with any problem you might find. So far its looking great! If anything try to keep lowering those temps or get the humidity at least to 60% because youre in the VPD danger zone and while that will probably not be a problem in the short term its not good in might cause problems in the long term.
I dont wanna saturate you with too much info so for now lets just cover the basics:
Vapor Pressure Deficit (VPD) is a measure of how much moisture the air can hold compared to how much moisture it actually holds. It's a key factor in determining how much water plants lose through transpiration, the process of water movement through a plant and its evaporation from aerial parts, especially leaves. Essentially, VPD indicates how "thirsty" the air is for moisture.
This is your current climate and here you can play with the parameters to get as close to good vpd for veg as possible

Now to cover more basics to make sure you know all you need to know to grow and there's no nasty surprises:
What medium are you using? What light model? Do you ph your water? What kind of water do you use? If its tap water do you let the chlorine evaporate? What nutrients do you plan on using when theyre bigger?
Suggestions so far:
Decrease temps or increase humidity, or both, play with the chart I gave you to get to a decent VPD.
Increase ventilation in the lung room (room where the indoors is located). In summer I put a big fan in my door facing outside so my lung room has more airflow when its too hot.
Your tent should have negative air pressure, meaning that the extraction fan should have slightly more airflow than the intraction fan, that way you ensure all of the hot air goes outside instead of forming hot air pockets. If your extraction fan has more airflow, which I assume it does, then youre fine. If you notice that the air is still too hot compared to the lung room, close the windows of the indoors, sometimes that can fuck up your negative air pressure. If you do that and your tent starts shrinking too much because it has too much negative air pressure then try just leaving 1 open. If it only shrinks a bit thats fine, you have a sturdy tent, its normal when you have negative air pressure.
That said: your tent looks nice, I hope you have fun here and with your grow!
