Okay, so I'm on the third week of flowering and have just fed fed them for the second time. I took your advice, 420, and used the Fox Farms Big Bloom and Tiger Bloom, although i bought them separately. I am watering them every three days, and feeding every other watering. Theres two 42 watt red spectrum cfls and two 26 watt blue spectrum cfls per plant. I am planning on adding two more 42's to each plant soon. My indica plant on the left is doing very well, the bottom leaves have slowed down dying a lot. The sativa plant on the right, however, is still killing off the bottom leaves at the same pace as always. Also, it seems to be stretching up towards the lights a lot more even though its they're just as far away as they are on the other plant. This plant did start to develop a few swarms of fungus gnats, so i treated both the plants with pyrethrins and have yet to see another one. Thanks for the help everyone, especially 420. I'm still open to suggestions/comments!
Here's some pics
First pic is both, then three of the sativa and three of the indica.
