my new gbp morphs are doing the same thing? are those safe crackers on the right? mine are very dull. but... the new ones that i have recently recieved were duller when i got them are coloring up. my beginning zoas most all of them got duller when underneith pc lights but i didnt have enough coverage then. the gbp's look almost exactly like yours now and they are under t5's and halide. not sure i have been a help,lol.
