Which one should I use for foliar spraying on my home-grown, cured tobacco?
It seems like my soil was lacking a sufficient amount of potash — the combustibility is pretty bad. To fix this batch, I’ve read that I can top it up with one of these. The bicarbonate is less alkaline but might not be as effective as the carbonate. Has anyone experimented with both and can share their experience? Cheers.
