Diatomaceous earth problems!

I got a bit of DE on some leaves thinking hey whatever, everything i have read about it tells me its no big deal… its even safe enough to eat… blah blah blah.

Now the leaves are turning crispy and wilting but keeping their color. Help.

(background: there was an infestation of small bugs that grew into bugs with wings due to previous overwatering, repotted n new dry soil with DE on top)

Just spray it with water.

It can physically cut some things [this is how it works as bug control] or it could plug stomata's because of how small it is and plug air flow in out out of the leaf.

But usually it is fairly inert. I have used it for many years without any problems........

Nothing (IMHO) will get you coughing up blood than using DE on your plants in any way..! diatomaceous earth, is used by gardeners doing vegies ..and are eaten rather than inhaled, see them for what it is,,but millions of tiny razor blades ripping the fuck out of your lungs with every toke ...I shit you not!!
Dirty gardeners use this shit, as a trick to try and tell their customers that they are green or organic, don't be fooled you got bugs, clean up your grow space, make your plant healthy ...its easier than spending a fortune in an iron lung!
Many alternatives exist before you spend the rest of your days again toking in a iron lung

Yea i thought this stuff was safe but now that i've put some water on it i'm really worried about it. When wet it turns into a sludgy concrete like substance that seems to just plug up the soil. How can this possibly be good for a plant?

I'm wondering if instead of a thick layer at the top, if sprinkling a small amount into the soil as a preventative measure is a workable option. I don't see this stuff listed in any supersoil recipes I've come across though….
