Safety concern with my tinctures

I have a batch of glycerin tincture that I am making with trim, I dont think the trim was dried properly or something and I was gonna throw the tincture in the garbage after noticing black spots that I thought was mold... but for some reason I am still flipping it every day... (When I started the batch I was away working and my partner kept forgetting to flip the jar so for the first 2-3 weeks it was flipped every 4 days...)

Meanwhile I started another batch with grounded pot, trim, and buds ... now when I look at the trim closely in the jar, I see the same thing is starting to happen... what is going on? is this not mold but simply the leaves absorbing the liquid and turning darker? Should I not be using trim in my tincture? (I keep thinking that mold wouldnt grow in glycerin as well... am I wrong?)

Sorry it's hard to explain and it 's even harder to take pictures of. Basically I want to know if it is safe to use and if it is normal. I have someone that tried a batch I made a couple months back (that was 100% buds and nothing like this...) and it is really working for her pain and if this is stuff I am making now is not good, she will have to wait longer for her medication and I will make a new batch using only buds but if this is good I dont want to throw it out.

Thanks.

ok in case anybody ever come across this thread....

after further inspection, I opened the glass jar that contained leaves only, and when I picked up some random leaves and looked at them with light, it`s not mold at all ... (I was pretty sure mold wouldnt grow in glycerin... I was just being the usual parano pot head) it`s basically the leaves losing the pigment or something, what I thought was mold is in fact a discolouration of the leaves at random spot, so if I put it up against a light I could see through the leaves... in the jar though looking through those holes make it looks like dark black spots on the leaves.

Anyway, all is good
