Thanks Stinky. I'll try foliar spraying next time.

While I think CalMag is a great product, it does raise the ppms quite a bit and that concerned me. Last time I added it to my reg. nutes my ppm was over 2400. And that included only 70% strength per Fox Farm nute schedule and that was at end of wk 3 or beginning of wk 4.

I believe most manufacturers recommended rates of application are very high for indoor use. Since they are in business to make money they will recommend the highest dose they believe they can get away with.
