So I have a CFL grow in a 3x2.5x4.5 area. Just added a home made hood with mylar on to reflect any lost light back at my baby's. Everything was cool. Then the top leaves around the buds slowly started rolling up at the margins(not curl up from the tip). Well today after the lights being back up for a couple of hours. I took a peak and it's gotten worse. Some are even turning brown and withering up. I raised the hood a little to get the lights back, but i'm using cfl's! Is it a heat thing or nute thing. I even flushed out the soil. Please help!
