Thats the one I would get. And if you ever want to test soil pH or coco pH, you can order a "spear probe". Thats the model I have and it's awesome. I have the Bluelab Soil pen and their liquid only pen as well and the Apera stabilizes faster and is super accurate.

Always store the rinsed probe in the KCl storage solution. This will be the best thing you can do to keep the probe good.

This diagram shows that Sulfur stimulates Calcium, Molybdenum and Copper availability to the plants and that Zinc and Molybdenum both stimulate Sulfur. So I don't see an issue BUT if you saw something being locked out by excess Calcium, Molybdenum or Copper then perhaps the sulfur is the actual cause.

As we can see in this chart, excess Calcium for example, could limit potassium uptake.

Every element has it's limits so how much sulfur can we have without issues? I really don't have that number.

Me too! I also miss White Castle, sometimes I get a craving for those belly bombers. I don't even think they have a White Castle in the whole state of Colorado.

If you ever find yourself in Fort Collins.. Big Al's has a very nice burger. Freddy's and Big Al's were my spots. I've only had those microwave grocery store white castle burgers :(
