What do you mean by cali/mag? I've read a lot of growing books, but it sounds like your are saying calibre and magazine.
So nitro deficiency? How should I solve that, I can't just up the mutes because they already look like they are getting a little burned...
Here are some extra infos on the grow if that helps. I am growing a single plant in a 4x4 in a 8gallon airpot. I am following the canna feeding schedule at half strength and watering once ever 2-3 days. Soil is canna professional plus. ph is about 6.5 and temps/humidity are where they should be. The strain is mango haze. Someone told be a shouldn't be feeding her at all which I dissmissed since I am in a pretty light soil( how is she supposed to get her food)
