Thank you for your help, but unfortunately the sick northern lights is no more. While doing some work to the greenhouse this afternoon two of the northern lights were moved outside in the sun to make moving around in the greenhouse easier. During no more then an hour of being out there the sick one was taken. I'd rather that the sick one was taken than the healthy re-veg, but still it sucks after the time and energy put into it. Anyway I'm going to focus my efforts on all the other plants now that it's out of the picture. And to answer your questions, the soils didn't have any Ca or Mg (or at least no mention of it on the label). The fert was FF Grow Big 6-4-4 which has .6%Mg and no Ca, i used the heavy feeding dose of 3tsp per gallon. I do have a pretty full bottle of Calmag laying around. Yes the Hydro is doing excellent, although I ended up taking over the duties of caring for 2 soil plants and that bucket, I feel like I just do better with that setup then with dirt (but I may just feel that way because it's doing the best on it's own). I'll try dialing back the fert in the bucket this sunday when i clean it out. Now that I'm a plant under my limit I'm planning on making another bucket. Thanks again.
