Hi cloud,
Lose the azalea fertilizer. It will kill your plants almost instantly because the pH reuirements of Azalea sp. are SO acidic. There are many cannabis-specific fertilizers out there that are easy to use. I think botanicare pure blend pro grow is the hardest to screw up for a beginner.
Add more CFL lights if you can keep the space from overheating. Yield depends on available light.
