At what PPM levels does it start to affect the transpiration? I doubt at a level of 1ppm it has any effect at all as commercial greenhouses use it as SOP...I have used it at I higher 4ppm with no ill affects at all. As far as nutrient interference... it will if you are using any organic...
Hey Fatman,
What is up with the Molybdenum? I see the other formulations for *uchMasters and the others do not have it. can I use Sulfur Molybdate? will that increase sulfur too much? it's a small amount.
