What is my plant missing?

I use living soil, environment is perfect, humidity temperature, etc. Running a couple plants that are crossed with PCK. They are the only ones with this issue along with other strange problems, but the leaves are turning a light green color and then getting very crispy. Only the bottom leaves , only on this particular strain.

Looks similar to damage from phytotoxicity, maybe a pest. Has this plant been sprayed or anything that could have caused trauma lately? Did you build your own soil or top-dress anything heavy? Can you provide some more photos of the damage from a couple of different spots, please?

I think maybe you nailed it might have been from them going into build a soil 3.0 blend from the light recipe.
That would definitely change things.
I also just transplanted into the soil
Also, I noticed from using the soil every one of my plants has a very rigid leaf. Not just one strain, three different ones.
