worms are most certainly in my soil and always have been.I gave them an avocado bomb last week with insect frass and oyster shell and they are devouring it as we speakAnother thing that will help with the availability of calcium is having a sufficient number of composting worms like red wigglers in your container. While microbes and plant exudates contribute to helping make calcium available. Nothing works quite as well as having lime, oyster shell flower, crab meal, or bone meal pass through the gut of a worm. When these are passed through the gut of a worm after being consumed as grit for the gizzard, they liberate the calcium into a form that is available to the plants almost immediately. It does require an acidic reaction to deconstruct the amendments into available calcium, and this may be the only way to ‘unlock’ the potential that’s in your soil in a fast enough time frame. A soil pH around 6-6.5 takes a long time for this process to happen on its own. As few as a dozen composting worms would make a difference in your sized container.
Just another thought I wanted to throw out there.

@Organic Sinse I also run those amendments through my worm bin but I am curious how often you feed them the amendments? and is that your primary feedstock or do you do food scraps etc. as well? that is interesting to know about your weekly top dresses! I have been always top dressing once at 30 days and again around day 50.
the more I think about it the more it starts to make the most sense that I have been just undersupplying calcium.Also my practice of not top watering in the past may have also contributed to not having the calcium available fast enough for the plants needs. I will continue with the EWC bone meal top dresses weekly as well as good top waterings to make sure the amendments become available as soon as possible.
