From what I understand it's always good to test your plants and gradually move on up in nutes. However, I use H&G at full aggressive strength and my ladies love it. Not a burned tip ANYWHERE! H&G is the main attraction for European growers. I don't think that's a misprint. Wait until you get Bud XL in the mix. Wheewwwww, you'll see those flowers get nice and wide and then BAMMM with the Top Booster where bud sights pop up galore. Then, then, oh yeah...then, Shooting powder!!! The boooomb dude. You will hit those lights and it will look like someone squeezed your buds because there will be thick new pistols screaming at the lights. It will look like Winter wonderland in your garden. I'm excited for you...you're going to have some fun watching your girls become ladies!
one month old clones shouldn't be in a dome, they should be in medium growing. you must have roots shooting out everywhere. aren't they looking kinda crappy? anyways, i'd start out with 1/4 or 1/2 strength at this point. what are they eating???
