well i think they're showing sex. 2 of the plants have balls and 1 has a bunch of small sacks with 2 little hairs coming from them. 2 males and 1 female? Id be pretty glad if thats what it was because now i can use all my lights on 1 plant and get a bigger pot for the 1 plant since their roots are totally filling the 1 gallon pots theyre in. ill get pics when the pistols are more visible.. theyre just about visible to my eye as my mom needed her reading glasses to see them haha
