Funny you mention this, every single grow I've had using recharge has shown mg deficiency/lockout issues. I've been chasing my tail trying to figure it out. I've been suspicious it's the recharge but until you said this no one else has ever really mentioned it.I mentioned no deficiencies with this grow. I bought a bag of recharge about a year ago. I dunno why I did, but I did. I mean, I have a lot of homemade compost though I don't like bringing it inside. I guess I bought the recharge just to try. It wasn't necessary or anything in my application. And I have often toyed with organic/non-organic fertigation. Though I don't necessarily consider anything that comes pre-packaged in a plastic bag, and then trucked around the globe as "organic". OMRI-ganic maybe? But you get the point. And I'm veering off topic.
I have found, that without fail, every single time I have used Recharge. Even a little. In a combination with FloraFlex. I get a deficiency/toxicity. Every time. It is 100% repeatable and provable in my case. I have even grown two plants side by side one with a little recharge here and there. And one without any whatsoever. Once again, the plant with Recharge always shows a deficiency to me. It usually presents itself as a mag deficiency too.
I've mentioned this before and people think I am bonkers. Anyone else? Well yeah. I have a friend that I turned onto Floraflex and he insists on using Recharge. He gets the issue. Every time. So...I'm not bashing Recharge. I don't think it necessarily necessary either with a healthy plant. Nor do I think it "hurts" in a lot of cases. But I obviously see issues with it and Floraflex. Just an observation that likely flies in the face of everything stated. YMMV. But yeah, no Recharge at all this round.
Thinking I'll just switch to living soil and call it a day.
