I believe this is caused by MC-139435

I found the reason it's happening! Whenever an element collides with or touches the neighbouring block, the ambient occlusion effect is applied. I noticed this issue when my pointed dripstone model got dark whenever there was a block nearby. My model was different from vanilla only in size of the planes. Reducing the size fixed the issue.

P.S. I hope that instead of making the spore blossom model smaller, the issue with the AO will be properly fixed

Update: tested it more and the AO seems to behave way more random than I expected. So the reason above is probably not the only one
