Once I got to the start of the second page my theory that I had was confirmed.
Soon as you said you are growing OG something, and Gorrilla Glue I knew the answer.
These American popular strains are all bred from hermies, so you will get some degree of hermie when you grow them.
They are obviously not full blown hermies as you would have noticed that, but there are male flowers in the bud there somewhere.
EastCoast and McKush - thanks. Glad to hear I'm not alone in this! My buddy has the same problem too, but he doesn't care about trying to fix it...lol.
I've had that thought about nutrients too. Like maybe it could be some type of "flower hardener" (cause this problem definitely makes the flowers "hard" lol ).
But I've been using all organic nutrients. No chemical nutes at all.
I'm still going to dial it way back to the very basics though. Just basically a single bottle of bloom nutrient and maybe a little bat guano.
I need to eliminate possible variables to this problem.
As far as sterilizing my room - I have sprayed down the walls and floors (etc) with water. Should I use a bleach/water solution?
Water is all you need to kill pollen
