I have some white rino three weeks into flower and alot of the leaves are curling up (from the sides.up) color looks good, ph was a little low just raised up the lights , ppm 1200. could it be a little heat stress. the room ranges betweem 80 and 95 degrees. I am goint to dump the rez tomorrow, just in case theres some nute def.

Hey HillBilly

The problem you'r having resemble this at all

(Picture courtesy of MyNameStitch- From The complete guide to sick plants, ph and pest troubles thread. Its saved as a 'sticky' in infirmary)

This picture is showing heat stress- I know trying to get temps down is hard, because if it wasn't everyone would be growing in an optiman enviroment-which many of us don't.

Raising your light up as far as you can without majorly compromising penertration and a fan blowing over the canopy will help abit-an air-cooled hood and better intake temps couldn't hurt either.
All this I'm sure you already know- just giving you a heads up

Best of luck mate

Just like they fold them down when they're thirsty, when they are drowning they tend to "fold" up along the center vein. If it's just the serrations that are curling, it's probably heat stress, any pictures? PS 95 is too hot

thats what they look like guvnor. I thought it was heat so I moved the lights up to 24" and turned up the exhaust fan. thanks everyone.

they just finished streching so hopefully the lights will be far enough away

.. the guvner had a very good point - try having your oscillating fan at canopy height..those on a stand are good.. this will blow away most of the heat that is beaming down on the plants.. i have used this method for many years.. no need for heatsheilds ..
grow on..
