I'm wearing out the scroller on my mouse tonight and I'm a little overwhelmed on the whole ferts thing. No rush on an answer. It sounds like you are quite busy from your posts!
Micro - nutrients that are used up daily by plants such as copper, boron, calcium, etc. in small amounts.
Macro - Your basic NPK (nitrogen, phosphate, and potassium) fertilization.
If you have dry ferts, here's
a link explaining how much to dose and how often. Dry ferts last longer than liquid and they cost less in the long run. You can buy them here
