First thing you need to do is check the sex of your plants before jumping to any conclusions. The easiest way is by the looking at the leaves. If they are symatrical (leaves on opposite sides come out at the exact same level) they are female.
Before anyone jumps down my throat for this type of sexing I learned this at my AMOP meeting. The know-it-alls that taught this class were the medical marijuana program sponsors in the county and our largest and stonest hydro store dude.
To see if what you call pollen is pollen or crystals you need a magnifying glass. I use one all the time. You can spot all kinds of things with this.
So don't jump to conclusions. Get a magnifying glass and check it out.
Um were growing inside and our plant is almost done and my partner just noticed a little yellow flower? whats that mean, beacuse its almost time to harvest her?
