Never use CFLs. They're a waste of time. But don't overdo it with the LEDs or you're going to stunt your plants. They'll start twisting your leaves and burning them as you're seeing now. This means you have too much light. A little ain't a big deal, but I've stunted them bad in the past even with just 2 12w LEDS at 5 inches height.
You need to start raising your lights a bit until they aren't stressing anymore.
People think you need massive amounts of watts in your lights. but that's not true. Basically, long story short, HPS are terribly inefficient and the wattage is a red herring.
