Why Are My Plants Starting To Show Sex

I have 22 plants outside and I was there today and I see that they had the first sign of there sex the lil calyx that start before pistles start to come out well some have few showing but very small plants started out shitty had bug issue eating leaves but now they are 3-4 ft tall and really looking healthy but will they go back into veg I also have 8 of them are fem seeds and they are small still maybe 12 inches 3 purple train wreck 3 critical + and 2 diafem cheese well hope the grow out before flower I live up north and its just been raining then few days sun n back n forth well I'll post pics

Preflowers is normal, they will show sex when they reach age ime. It is still vegging unless it's flowering, and will continue to show preflowers throughout veg, once it has reached the age to show.

Here's few pics the bigger ones are bag seed from some fire and others are from Herbie's

OK thanks bro this is my first out door grow and I haven't seen them in like 10 days and man are they growing nice

Here's more

Yea dude, those are looking like they are rockin' it out in the sunshine!

I've seen some strains throw crazy pre-flowers in veg (banana OG) but for the most part, vegging plants that are of age will show preflowers.

Good luck!!

Yea bro it was 10 days since I seen them when I took pics they are growing awesome I just feed the cal mag and big bloom first time I feed them should help I think they are going to get huge and its not legal here and they got long way to go I bet so and they smell and the are just fire bag seed I really like growing outside now it's my first grow outside well good luck and thanks
