Okay, I'm using a high quality soil mixture called Harvest Moon Just right Xtraaa. My first grow I grew dank, but I only got about 2 oz's out of 3 plants. I started used guano and molasses halfway through the grow since what I was doing obviously wasn't working. Long story short I switched to my mix of guano and molasses made into a compost tea, then the plants buds swelled and gave me a decent harvest.

Other than the trace minerals in the guano, and molasses of which have everything except calcium. I don't have money for dolomitic lime to throw into the soil, and didn't notice any deficiencies last time I grew relating to calcium. I should be good right?

With organics you feed the soil, not the plant. I don't know what the NPK values of your mix is, but you'd know if there was a problem. To find the NPK you can buy a $5 soil test kit at Walmart. Your soil should be complete out of the bag and the bat poop is just adding lost nutrients back in. Test the soil throughout the grow to see if your missing anything.

I trust tests more then strangers on a cannabis forum ;)

Molasses does have some calcium in it, but it is good to have a liming agent in the soil for calcium and to neutralize acidity. If you happen to eat enough eggs you can save and use the shells for calcium. I'd recommend rinsing the egg shells, letting them dry and then using a coffee grinder to grind them up as fine as possible. Dolomite lime is good if you can get it though because it also contains magnesium.

Nutrients in guano vary depending on the source but typically it is either high in nitrogen or phosphorous. Peruvian Seabird is 10-10-2 which makes it an excellent guano for the greater part of the grow period. There isn't typically much for potash in guano but that is where the molasses will shine. Liquid kelp or kelp meal is also a great potash\trace mineral supplement if you can get any. Greensand as well. But yes certainly I would say it can be done with just the right guano, molasses and a good soil mix. Guanos are also biologically active so they impart microbial life to the medium. If you had any compost or vermi and an air pump you could surely brew something good, perhaps even without the compost and just using a healthy guano and molasses.
