I see your below 85 degree, where exactly your checking tent temps? I kinda check in 2 different height's , maybe area around plants much warmer then 85, just a thought... It seems you have good air-movement with 2-16"fans & also extraction... so my best guess is maybe area your checking temps could be different then around your plants, seems very likely...****Also--your humidity is a bit low though for tent temps, I'd boost that up to 50-60%.(veg) 40-45% flower, then last weeks of flower 35% is fine... your kinda running flower humidity, while a seedling/start of veg.... give ya an idea my tent temp is 86.7...my humidity is 80%, I kinda go by vapor pressure deficit and have chart..that shows where keep tent humidity at what temps tent is at..I find it crucial for optimal growth...I'm using co2, that's why my temps are higher...just so ya know....
