I described it at my forum like watchin the Midnight Special with Boones Farm Strawberry Hill good LOL if you're as old as I am you'll get it
One of the clues that led me to adding sulfur was an article I read about farmers having to supplement it due to the switch to unleaded gas. Seems a byproduct of us usin leaded gas was more sulfur in the air. Somehow in my mind the dots got connected and I realized that the one thing that was different in the 60"s and 70's (when trippy pot was the norm) was that we were usin leaded gas and there was lead in the air because of it.
I shifted my focus to the Kulu Valley and the Charras mountains where the best pot in the world comes from. I found that lead was one of 3 minerals that was mined in the area and that there is an active volcano in the region. There is also a hot sulfur spring that runs thru the valley and it turns the drinking water white in several of the villages.
I also chose to start usin Azomite which is a volcanic dust mined in Utah. The ppm of lead in Azomite is 6.2, the organic folks at OMRI say that up to 300 ppm is ok. With this in mind I kept my doses very low mixing 1/8th teaspoon of lead sulfate to a gallon of water and gave different plants different doses. The Zamaldelica got 4 feedings, the Thunderfunk69 only got 2 feedings. The 2 side by side Borealiz plants one got 7 feedings and one got none so the difference could be seen? That will happen soon as I said I am harvesting them this morning.
