Is that a male pre-flower on that 5th picture? You...

Hey there a zoomed pic would be great to help us help you..however, male pre's tend to look like a spade from a deck of cards and typically at this stage are so small, they usually develop faster than females so you'll know soon enough. But if you're seeing more of a pointy shape its probably going to turn out to be female. The more round you see, and the more grape like structure you see...then there may be a cock in your hen house. ;)

This looks like a regular excrescence, keep us up to date with zoomed pictures but don’t worry too much! I’ll be around, happy growing bro!

The picture makes it difficult to be 100% but I’m only seeing female preflowers
