One is Female the other unsure...how long should I keep IT around?

2 feminized Nirvana Northernlight seeds grown in stealth pc growbox. They've been under 12/12 for 15 days and just today I noticed one of them showing the classic pistol white hairs shooting up however the other plant has much thicker "prongs or horns" but no white hairs shooting out and I'm concerned that this could be a male. How long should I keep it around as it is not showing any balls. See photo...I'll try to get a better pic tonight.

Just give it time.

Since you're working with feminized seeds the chances that its anything but female are slim, unless stress has caused it to hermie.

I wouldn't worry about it, some plants are just slower than others.

Blackvalor is spot on. Give it time, definitely don't do anything rash until you are sure it's a male (an extremely small probability). You'll be able to remove before it can do any damage anyway. Them ballz need to "age" just a bit before their dangerous

Good luck with your grow
