just plain water. i just used tap water. but i live in quite a hard water area so it sits at about 7.0, which the soil buffered to 6.2
Think I'm going to give them an extra week giving the fact that I'm trying to bring them back to health and I definately want them to get a little bit biggerMaybe wait one more week? But remember they are going to get tons bigger when you go 12/12 and vegging even a week longer is going to make them that much bigger...but I feel you on wanting to wait until they're healthy. Tough decision!
Ok thanks and I keep doing this through the rest of the grow rightLeave them man. LST isn't doing much of anything to adversely effect your plants.
