    One of mine got heat stressed and never recovered. I had to chuck it in the end. Other 3 were fine.. Mine were sitting in 34c though. That looks like it got way hotter than 80f....

    Too hot in there bruv see one of your fan leaf tips is starting to show ill ease as well,diff strains and even same strains can show up things at different times. so they aren't suffering but she still is. when you say room, what size, what extraction, what air in, what air circulation you got going on? couple of guys on here have asked how far away from the plants (inverse square law) so to help you properly, you need to paint a clear picture (words or photos) of what you got going on with your room :-) you got buds going on, you want it sorted soon :-)

    Have you got a thermometer in there telling you the temps

    also the fan size is dependent on what volume of air you want it to shift, i.e your grow room size, so....(LxWxH) and multiply that by 60 will give you the max volume of air to to shift per hour,

    remember you filter and ducting can decrease extraction performance significantly,

    I doubt a mini whisper fan will suffice in circulating the air when your growing have a read of this mate

    I didn't mean the intake or extraction fans, I meant a fan in the grow room that keeps the air moving about and prevents hot spots....
