heatstress the leaves curl down to get away from the light.


this looks like a nutrient problem or underwatering.

Maybe to much wind or cold...

and/or too much wind.

The leaves are drying out

Sorry man, but that is incorrect. Leaves always curl up when they dry out due either to too much heat, to little humidity, or both.

What this guy has are the classic symptoms of heat stress.

usually heat stress when the leaves fold up like a slice of pizza, what i would look at is if its hot enough to do that to the leaves, then it maybe too hot for the water in the rez, is it me or do the plants look a lil pale?

thank u guys/gals so much , really i think i got it , but just to clear the air im using a 18 gallon tote how much water to nutrients do i need and how much water? i usually go half of what the bottle says , so what do u think? 2 air stones , water pump and cfls, which i think are less than 100 watt ech when it comes to comparison.... anyways just got back from the wonder full store of colors and smells......

everything sounds good purps, just keep an eye on your water temps, i dont believe you can do too much heat related harm with cfls, maybe plants that size are better of running at 1/4 strenght, i have never used flora nova so i wouldnt know how potent it is. you have a ppm/ec meter? personally i would run plants that size 400-600ppm, and stay ontop of that PH dude!
