I’m thinking my blue dream has rust fungus it looks like sulfur or baking soda is my two options I tried rubbing the spots but it’s not coming off on my fingers but I have two fans going so it may have got airborne but none of my other plants are showing signs yet??? Any help would be appreciated I noticed the leaves are all mature and very brittle image|375x500

I thought it may have been the light at first but it’s not hot at all around the top of plant. I did have the light a little close at one point and changed it as soon as I saw an issue with one of my other girls so it may have been older damage just showing now i guess

Sky - maybe this will help a little
It looks almost like a calcium, maybe mag and possible some phosphorous issue
Usually with mag issue, you get some yellow between the veins. Your fans look very green, is there much nitrogen in there? Might be cutting off the absorption capabilities if so.
If these are LOWER leaves, it is a ph issue
Hope this helps

@Skysthelimit that looks like a mag deficiency and like you got your nutrient mix on the leaves with lights on. Those white calcium spots by the burns are the nutrients left behind by the evaporated mix.
Make sure to water and feed just before lights on and don’t get it on your leaves.
