Smell like burnt grass.

GWE,

Is it normal to have some flower smelling like burnt grass. I recently observed a few days with the RH below 20%.
Did i burned them?

It was weird my plant would smell up the tent in veg with a weed smell and then about 2weeks in to flower it stopped and almost all smell went away.

Now that I'm at week 9 of flower it smells like medical grade from the store haha.
