Yeah, I'd check with the local AG dept and ask them about that. My guess is that you're needing some standard nutrients, nitrogen, phosphorus, and potassium (N-P-K) .

Your ag dept can tell you what mix works best for your area. I take my egg shells and crush them up to add calcium. Tomatoes suck that up.

Here, we also have to add a lot of lime to the soil. Now's the time to be doing that for your garden here. I will be adding some this next week, as well as some composted manure.

Be time to plant potatoes here in just a month.
