Yes I have even had what looked like balls show up first and within a dot or so they will put out a hair. Fortunately for me I have never seen a male in person just pics
See if you can get a better angle but yes it looks like it is preflower
Like this one, it is a female these just havenāt spit out hairs yet but they will in a day or 2. Me personally if I donāt have any of these hairs by week 2 from light cycle change I wold get concerned. I did notice that if you donāt have a good light source it takes way longer for them to show
Thatās male pollen sacks dude for sure

Yay!! Hurts enough to pull one. 
I know the feeling
That sure does look like a hermie to me . Get it away from the harem or just kill it if you canāt seperate it with absolutely no chance of getting the girls pregnant. 
Wow,!..thanks to everybody! ā¦what a great forum!..Iām relieved to study the input and examples, insightā¦Iām still a little frightened thoughā¦I reallyā¦really.
