I’m using this shader and when it collides with my pointlights it becomes extremely buggy and white-purple.

my shader code:

Blend OneMinusDstColor One

source color is multiplied by 1-Destination and added 1*Destination…

having trouble mentally seeing this but
(light * 1-grass) + grass?

OneMinusDstColor would turn green → magenta

It kinda looks like that can be part of the issue… but the instruction confuses me as to what it was trying to accomplish

Do you have any idea what is causing them to glitch to white?

place saturate( ) around your output in fragment shader, see if it fixes it.

Are the normals for the mesh OK? How does it look for a Unity sphere - lit correctly?
