Plant has a strong smell like hay all the way through flower. Is it bad?

I've never had a plant have a strong hay smell during flower. I've done this strain a few times before and it never smelled like hay. The thing that is different this time is I used something called Floramax Resin-xs as I was told it would help with certain things. I can't find anything which says it will change the smell.

The plant is ready to cut and the bud looks normal. A few tops did burn a bit because they grew too close to the light but I don't see any signs of mold such as white cottony stuff or web like things.

I tried to search google for weed plant smells like hay and all I get is a hundred things about drying weed smelling like hay. So that is no help.

Anyone have a plant smell like hay and is it a concern?
