Can I sex from these pre-flowers?

Hi All,
I've just finished the last of my vegging stage on 24H, and have just switched my lamp out to red 3 days ago.

I'm pretty sure my plants are pre-flowering and before I start switching down to a 16/8>12/12 I was wondering if I could sex from my preflower, I'm pretty sure my other 3 are females but this'un im not sure about, feminised seed too.



and same plant



thanks in advance

You can sex them. look for litle white hairs coming out. use a magnifying glass. Fem seeds you should be right but dunno. hope someone more experienced can help you.

Yea i would say that that is a female.Look for where the internodes come out and on a female you will see 2 like shap looking growths on the stem going up the main stem this is a sign that the plant is female.But sometime's a male will also show this trait.So my advice would be take a clone put it into some rooting compound then leave it for a week feeding only water and superthrive ph of 5.5.Once the plants has roots just give it a gentle tug and if it feels has though it has a hold then bang it on 12/12 off feed with flowering nutes and give the clone 24 hours of total black out.This is the method that has always kept me in good stead then lable the clones before doing all this so clone a come of plant a.This means that you can ditch the males and keep the females.

I cant tell cuz I cant zoom in on those pics. Like g4me said, use a scope
