What's ur light cycle? 18/6-20/4 or on 24hrs? As changing wen ur light when it comes on make a massive difference, so say the hottest part of the day have ur lights off, run it mainly in the evening when it's a lot cooler, Also Get a OSD tower fan in ur tent, notice u haven't got one in your set-up, this will help move the air about and will also help ur lady's build a strong root from the breeze, run ur carbon filter and inline fan, this will get rid of the heat and stale air that builds up in ur tent and run the filter to ur light cycle...... Humidifier also helps cool down a tent, as these produce a cool mist and drop temps by 2-3 degree's...... Run the humidifier to ur light cycle or a quick fix is a bowel of cold ice in front of a fan helps, it's a good cheap fix and would help with humidity!!! Aim ur clip on fan just below ur lights as this will push the hot air away from your girls that's ifu have not done that, open the bottom side vent and use a fan (outside of your tent) to blow cool air into your tent, I'm jus giving som idea's as I've suffered from high temps this summer and it's a right pain in the arse, and "Your Girl's With Suffer In High Temps" and slow down loads, trust me I know as I had that problem, if you don't correct it bro, and remember auto's only have so much of a time frame so the clock is ticking, so to speak lol. Hope this helps, I'm sure one of the pro's will com in and help, but do get them temps down as high heat massively slows down the growth. Hope the rest of ur grow goes OK bro!!! Will sub this peace ✌
