Eh, maybe it's a placebo effect. I've got so much humic/fulvic/kelp around....I've been just spraying the Mac's with the mix when I'm spraying other stuff. Anyhow, those giant leaves don't seem to be showing heat stress, crisp edges, etc this year. Eh, probably a placebo effect....

Ain't costing me anything just short of time spent on the extra TLC I've giving them
