I also don't think that misting is the problem now. I was reading through some of that online grow guide from overgrow (it's cool) and the symptoms (yellow leaves but dark green veins) is an Fe defincency caused by the soil having too high Ph due to it's high organic makeup (you can see the rotten wood chips and shit in it) and also can be from the water Ph being too high locking the Fe out. My Ph meter "is in the mail". The UPS tracking site says it should be delivered tomorrow. So another guide said you could lower the Ph with vinegar. So I put less than 1/4 tsp. in about a qt. of water and watered my plants. They were due for watering anyway. I'll go get some dolomite lime tomorrow. and hope the meter gets here. Well lesson learned. Don't use cheap-shit soil.
