Mold?!

I'm having certain buds drying out while on my plant. I've harvested them thinking they're usable, but I have noticed they are semi dark in color.

I'm in my last couple of weeks of flowering and I'm currently flushing with ph'd water. Nothing else.

Here are pics, and I hope that I am wrong.

I zoomed in and I really can't see anything dark on the bud except the third photo on the sugar leaf I do see a little dark area. How about breaking the bud open and checking it out does it look ok? Have you looked at your plant under normal fluorescent lighting to see if it is finished? I've noticed with some strains if the nutrients are low they will tend to just out right die versus attempting to enter into rodelization. It's not impossible the dark area is simply degraded thc, which you can test by trying to melt it on tin foil in the oven if you can scrape it off.

the first one looks OK but the other two look like mold. There''s a product called https://bigtimezyme.com/shop/product/exterminator/ they say it kills mold and leaves not residue and can be used on flowering buds right up to harvest..

Thanks guys, I hope it's not mold and I will keep a close eye on my plant.

Here's an update. I still got larfy buds drying out on the plant. Plus the top of one cola who is rapidly turning brown.

Plucked the dying bud and further inspected it.

There was no sign of mold but I could be wrong.
