From their page, the tomato one at least should have:

The amounts are good (one needs to consider the fact that all values will be divided to 2.5, since you add the calcium and magnesium stuff). In fact, the values are much higher than the base stuff one finds here in Europe, the higher values are more in line with other custom formulas around the net.
They don't say what form they are in however, probably the iron is edta, for sure, but who knows about the rest.
Chemgro has iron dtpa (much better than edta for hard water), but manganese is only sulfate.
Greenway biotech has all in edta. This one also has even higher values, especially for Zn and B.
