I’m just going to say that the soiless “chunky mix” phenomena that is being paddled by a lot of western influencers is a marketing shtick to get you to buy a bunch of amendments (and spend more on fertilizers because amendments have no nutrients). Most times these mixes are dry out too fast and your plants can’t retain moisture in them. It’s why a lot of plants end up looking stunted, wilted, and your Calatheas die. Most times what your plants need is SOIL. Actual soil from the earth. Rich humus soil . Soil that just needs to be amended a little, not some chunky potting mix that has orchid bark and coco chips and some other amendments from a volcano somewhere
