I grow indicas in partial shade in the woods. They do fine, but indicas tend to have more dense buds so you have to watch out for bud rot toward the end, when it starts raining. You may have to harvest early, while with a sativa you might not have such problems.

Yes you should be able to LST a sativa outdoors, but some don't like it and some don't mind so much, so you might just have to experiment a little. I'm not a big fan of LST since it produces massive amounts of small buds. I like topping better since you have more control over size and amount of buds that way. On the other hand, for outdoor plants you might want small buds so that when they get heavy with resin and rain they won't break.

I'm by no means an expert problem diagnoser, but the tomato looks a little wilted, which can be either under or over watering. For dirt plants, make sure you let the soil dry out as much as possible before watering again. It won't even hurt to just check them twice a day until you notice the first signs of thirst. The yellowing leaves toward the bottom might be an indication of Nitrogen deficiency.

Also, I'd want at least twice that much light for all those plants. Your plants will grow that way, but they will stretch and results will not be very exciting. They're a little more expensive, but I would also throw in a daylight, or cool light CFL (5400-6500K, preferably 5700). Your plants will be more bushy that way and yield will be a little higher.

Good luck.
