Maybe it is due to the fact that I also use Milorganite and some Osmocote. Due to the expense only the favs in my eyes 
get the Osmocote. Like last season I got another container real cheap this past winter. Patience 
:rofl:. I will be trying something new to me this early season to give them the micro nutrients that they should get in the early season from what I read by a big name hybridizer. Iron, Calcium and Magnesium among others.
Just a note, Milorganite contains a lot of iron, I wouldn't add any more. If you feel you have a deficiency of iron you'd first want to look at your soil pH. Quoting from a Milorganite document: "MILORGANITE is guaranteed to contain a minimum of 4% iron—almost as much iron as nitrogen." Is the Osmocote one that includes micronutrients also? If it is there's also going to be iron in that.
If you have a problem with iron deficiency you also wouldn't want to add calcium because, depending on the source, it is used to raise soil pH and that decreases the availability of iron. It probably wouldn't do much harm to use Epsom salts for magnesium if there's a reason to suspect a deficiency (more likely on an acidic soil, in which case you're less likely to be having problems with low iron). Also calcium and magnesium are major nutrients not micronutrients.
Not sure if it's been mentioned before, but I would suggest getting a soil test before changing the balance of nutrients in the soil. Yours may not have the same needs as the "major hybridizer". If you apply too much of one nutrient it can cause a deficiency of another, or be toxic itself.
