Hello gin You have certainly done the right thing by reading up before you started growing, that really does help

You started them about a month ago, they are coming on ok, you're doing fine
Yes if you can get the money together, try and go for a ballast that will take both the MH and the HPS bulbs, that really is the best combination.
However don't worry they look healthy and they are coming on as they are now


Yes if you start them on the flowering cycle when the smallest is about twelve inch you should have plants that end up about two foot or so. That means they should still get light at the bottom.
