Thanks Noods, I'll be careful but with the BH I just used the water wise potting mix alone and it did seem to strong for it. The Cobra I mixed the water wise about 30% and then about 70% of the growes mix that says safe for seedlings and cuttings. The Cobra seems to like it very well and I'm only giving 1/4 strength nutes with good results so far. Her first nute feeding was around 14 days with about 8oz. You guys keep an eye on me so I don't screw up to bad
