Unless it's summer time and hot outside, I would not be taking my plants outside. Also, going back and forth stresses the plants, with the different kinds of light it's getting everyday. Further more, by picking up the pots and setting them down, shaking the plant, stresses it too.

If you are in Veg state, you need metal halide, not high pressure sodium, which the latter is for flower time. By the looks of it, it could be a pH problem which will cause a nutrient deficiency, so I agree with what previous posters have said. If you are doing 4 or less plants, a 600w is just fine by itself. You can get a light that comes with a ballast that accepts both types of bulbs. As for nutrients, again great advice from above to get a nutrient "pack." Your local nursery has lots of these and you can pick up a good quality of nutes and such. You are doing soil, so a ppm meter isn't required in my opinion, but you really should get a pH meter (digital). I hate those strips, but I am lazy. Anyways, when you add nutes to water the pH if you live near me, gets down to about 4.0. If you consistantly put 4.0 pH into soil, its going to cause problems. If you buy pH uP and get the pH to about 6.5 each time you feed, your going to have success. Hope this has helped.
