I didn't have much trouble 'till later in the grow with them.
I think they may be light feeders. In my hydro all plants share their water, and the dope is the only one with tip burn. I run them at 1800ppm,Ph 5.8 but don't have auto fill. When the water drops (they drink about 4-5 gal. a day) ph gets out of whack, and ppm goes up. The dope does not like this.
All others prob. don't dig it either, but they don't get leaf curl, or tip burn like the dope does.
As far as the smell goes, you aint smelt nothing yet brother, you are in for a treat.
I'm sure you'll get it figured out, if not let me know.
