Foliar spray. Currently testing on a 4×4 tent of cannabis in week 3 of flower. Will be running tests on our toms this summer where I can get a better scientific observation. My expectation based on what I’ve read is that it is an effective means of getting calcium into the plant although I won’t limit my application to just foliar, I intend to drench as well and compare against a block that has dolomite lime added prior to planting and then a control block with no added Ca

Thanks for the paper will give it a read. The image you attached needs to be attached as an image or it won’t render unfortunately. Some sort of weirdness to this platform. Not sure why it considers the two attachments need to be separate.
