Chlorine is easy to filter out, all you need is a carbon filter. You can buy water pitchers with carbon filters in them at most stores. They can't filter out salts though.
Yeah, you could leave the top of the plant on. I just figured if you cut it off then the branches might grow better.
With the fan, just try to make sure it isn't enough to make the leaves move around. Actually, speaking of air movement, I read that it increases growth if you have the air moving from above the plants downward, instead of upward. From the graph I saw, it looks like about 10-12% more growth. Just need to make sure the air comes in below the lamp so it doesn't pick up a lot of heat from it.
By the way, you don't actually need a fan to blow the plants around if you want to shorten the stem growth, all you need to do is rub the stems between the internodes or brush something across the tops of the plants, as the article I linked explains. Basically, it appears that moving the tips of the shoots rather roughly suppresses stem elongation by 10-50%, usually around 20%, at least in tomatoes.
About the spray, it looks safe and is supposedly good for spider mites. As long as it's only in vag stage it should be okay. I certainly wouldn't spray it on buds though. I'm sure it wouldn't taste very good or be safe to smoke.
