Just getting caught up here- It's good to see the Hound on the Rebound and I know you'll keep at it. I wish I could send you a giant care package of caramels, but the best I can do is give you the recipe if you're interested in adding that to your growing skills collection.

Generally, don't pre-mix ferts and sprays if you can help it. They are packaged stable, but at different concentrations and in a solution of your tap water that contains other chemicals and exposed to light, they may not be. I find that a small syringe with graduations in the 1mL -10mL range (just a regular 10cc syringe) is GREAT for measuring small volumes so you don't waste nutes.
