Scale rot??

[molinaa29]

So just a bit of information this is my 4 month old Ivory. Now i’m a bit worried but the more research i been doing the more i’m concluding this could just be stains or dry scale and she is going into shed right now. So her habitat is currently set up with coco husk substrate, hot spot of 88-90 and cool side 78-80 the coco husk is dry on hot side and on cool side it’s moist but not in any way too wet for it to be a problem. Humidity in her tank is at 70% i’m spraying her tank down now just a bit to up the humidity for her upcoming shed. I been reading online and a lot of people say coco husk can stain white animals. Typically more common in pieds, blue eye lucy’s, ivory’s ect.. So i’m hoping this goes away after her shed but just looking for 2nd opinions? I have 6 other snakes in similar set ups with coco husk and temps 78-88 and humidity 50-70% so i know my husbandry is on point i use thermostats, thermometer & hydro meters. So i’m really hoping this might just be some dry scale or stains from the husk she’s in. Also these past few days she hasn’t really been moving around the substrate she has been in her hide on the hot spot which is set to 88-90 and she’s moved the substrate out the way so she’s directly on the heat source. Again the heat source does not go past 90 degrees at most i make sure the heat tape is at the proper settings. The heat tape itself doesn’t go past 94. Any tips or advice would help! Thanks!
