m0useanswered grow question 3 years ago Nice looking plants!!
I can't say I know much about that stain. Have not grown it out myself.
It does look a bit like clusters of popcorn. Almost like a dessert snack, OMG's?

The one humboldt seed UK Cheese I grew did something similar to this but not to the same extent. Makes trimming easy and I really like how it looks after.
Sorry cant be of real help,
Happy Growing!
