Did I miss the boat...
Did I miss the boat... again?
I thought I read that Foliar-Pro and Pro-Tekt created negligible salt build up, but the rim of some of my pots are covered with the residue and the some of the plants are having problems. Interestingly, the plants in trouble, are specific cultivars, from a a certain hybridizer.
They're in the "Gritty Mix". I was using ES and did use gypsum. (I've quit using the ES due to these problems.) Is flushing the only solution?
