Yeah man, those are pollen sacs. From what I've learned, they can show signs of pre-flower which really help identify males and females early in the grow cycle. I grew from regular non feminized seed and mine showed 6 weeks into veg (yes i was in veg a long time) and allowed me to yank the boys out before flower even began!
Well well well, Riddle me this:
How has the Father plant this cutting came from, not shown ANY signs of preflower it's entire veg cycle since last year and just the cuttings from him have?
This is very beneficial information though, I now know out of my remaining four vegging plants I have 2 males and 1 female.
I lost my ID tags initially on the two female plants I have in my tent now but it can only be either orange or magenta. Cyan and purple are male.
I can now safely move the males outside to grow outside. I have enough seeds now that I don't need to worry about them dying.
And the lighting conditions aren't enough for four healthy plants but two healthy plants for sure.
