Heat stress?? Help??
- Thread starter Professionalgriefer
- Start date
What type of lighting are you using and how close to your plants? What are your grow area temps?
Using 600w hps and a 200wcfl now to far away moved now though as for worse after this photo have a fan blowing constantly just think I had the lights too close? Don't have a temp jig till arrives in post tomorrow
Hopefully moving your light up will help. Temp should be around 75f to 80f give or take a few degrees.Also just keep a slight breeze moving around your plants not to so much as to dry out the foliage.

.... like Nammy said, your temps, RH and breeze strength matter! Any combination of higher emps, low RH, and overly strong air circ' can combine to cause heat/transpiration stress... this shut down the the flow of pretty much everything, as the stomata close up in an effort to stop moisture loss, even if the soil is plenty moist itself; different strains will have different tolerances too,... how high up from the plants is the light? ...proximity intensity can cause this as well, hot spots if you will,... for now, until you have temp and RH reading for us, cool it off in there, get that AK in less intense light/heat, and away from direct blasting from fans,.. if it continues for much longer, defc. issues might start up...

..hey bud! What's with the droopy leaves, is that from going too dry, or from a heavy watering-- both can cause this, ironically! ...looking at the gauge, it's too warm and way too low RH in there,...these will cause water/transpiration stresses,... you need to get the temp down like Nammy says, and that RH needs to come up to at least 40%,...Typically, the best thing for this is a small humidifier, but even hanging a wet towel in there can help, but maybe not enough in your case-? getting the temps down will aid in raising the RH too,... life with HID lighting-- heat! 
.... the air coming in, it's 85 degrees? that's a major source of the problem right there,...
