Foliar feeding is proven to work, its not a myth and the science is out there. On healthy plants its a waste of time IMO, as it is impossible to force feed plants. If you feed a healthy plant via foliar, she's simple absorb less through her roots.

This is a tricky one. Not sure if been touched on.
Arguing with a friend now. So I thought it would be a good one.
But if myths that might cause conflict of interest to vendors might be a bit too touchy.
So. If fair game. I'd like the foliar feeding subject touched on.
I think it works. Friend says myth. Reading on the Google says a bit of 50 50 yay and nay.
Cheers!
