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.
grey1223 Reviewed by grey1223 on . Mag consumption chart I can't find the chart. Seems there was one on this site years ago. It showed the life cycle of the plant and how much is consumed at each stage. The reason I ask is I have a mag. def. with this strain I'm now working with (cheese). I believe it starts immediately after put into flower. Symptoms show at about day 7 or 8 (burnt leaf tips) and by day 14 I'll start to see the the interveinal nercrosis. I assumed CalMag would resolve this. So next time I'll start boosting the CalMag while Rating: 5
