    Ah K-Mag – where have you been all this time? Never heard of this kind of mix before, and I find it very useful as a preventative measure against deficiencies that *might* occur. I’ve only used it at the strength mentioned in the mixing instructions. I’ve applied it on both mature and (very) young plants. The clones are sprayed at 2 weeks and the flowering plants are sprayed within the first two weeks of induction, while their metabolism is changing. These applications help prevent mag / sulfur deficiency, and I swear the clones look better even 24 hours after application. My only gripe – I wish calcium was thrown in this product, but I use their limestone powder as a top dressing instead.

    Great Stuff, really helps give that extra boost to my flowers Very impessive blend used either as a drench or spray for high performance maintenance during all growth stages but mainly during 3-5 week works for me.

    Solid product .. been using it for a year now. Real nice shot of potassium, magnesium and sulfur. Gone up to 5 TBS per gallon once per week in flower with no ill effects.
