Calcium pellets

I was under the understanding that in small doses it won't lower PH enough to cause any issues.

It's not about the pH.

Because your soil was low on alkalines. Notice I keep recommending an end result with 3:1:2 NPK ratios.

Is there a better way to deliver available calcium?

Ensure your plants can obtain Ca from your soil. Is it low in Fe? Is it too high in P?

As a last resort, I would apply Ca as a foliar spray.

I saw it only cost $12.00 to purchase but $47.05 to ship it.

and @TorontoJoe
Calcium Nitrate is used extensively in the fertigation of certain crops. Farms buy it in equal amount with a complementary water-soluble, e.g. NPK 3-6-13 + micros for Rubus grown under high-tunnels. They are sold separately because those two sets of ingredients at those concentrations cannot be manufactured in a single water-soluble. On the other hand, it's no problem to add them both to a fertigation tank containing an appropriate amount of water.

As for shipping costs, farms order it by the pallet from a regional factory. It's not unusual for them to order 10 to 40 pallets at a time.

The best information I've been able to determine is that I am low-ish in Ca and Fe.... and depending on where I test, slightly low to slightly high in P. The University of Guelph has a soil testing program that I plan to take advantage of this year in hopes I can better dial in my ground soil. I don't know if they can help with container medium.

I think the biggest issue is that this isn't a tilled farm where all the soil is blended well across the property. In some areas it seems loamy and lush and rich... A few meters away it's clumpy, dry clay. I try to add as much organic matter as I can regularly to try and balance things out.... It's a constant balancing act.
