Plants not flowering!

Ok so this is my first grow and I have five plants in my closet right now (you can see my journal for my complete setup if you care) and they are on their 16th day of 12/12. 4 of my five plants are not (or at least i think they are not) showing any signs of flowering! My one plant that is flowering, I am 98% sure is male, at many of the nodes there are 3 or 4 balls growing so i believe it is male. (i included a picture of the males balls so you can see for yourself but its really blurry and might be useless) What is really confusing me is this, on the nodes of most of my female plants green things that look a lot like female preflowers they even have 2 things sticking out of them but there are a few things that make me think they aren't preflowers, first what would be the calyx appears to be made of layers of little leafs instead of one piece like picture show it and what would be the hairs sticking out look green and like the tips of leaves not white hairs. the biggest thing that makes me almost positive they aren't preflowers is that over the past few days they have opened up into leaves. I think they are just new growth tips coming out not preflowers and if they are not preflowers then there are no other preflowers of any type on them except at a node or two where a tiny green dot has formed but its only at a node or two so that seems strange. It just seems too coincidental that they have 2 things poking out of them and all four of my none flowering plants are covered with these new "growth tips" and my plant which i'm sure is male isn't growing a single new growth tip. I have included pictures but they are a little blurry because my phone cant take any better close-ups. Just so you know the first pic is the best I could get of my male plants balls, pictures 2,4,8,9 are all of the growth tips/preflowers picture 3 is of the growth tip/preflower bloomed and the others of just my plants (front left is the male) and my plants are 1 month 3 weeks old I'm just so confused please help

you 100% sure you dont have a light leak?

give them another 6 or 7 days. Some strains are slow to show.

Sativa? Takes awhile.

Ok I'll just give them a few more days and hope they show. Up until 3 days ago i left the closet door open all the time just a crack but the lights turn on at 10 am and off at 10 pm so sometimes a little light leaked in. I didnt think it was a big deal until i read something that said a little light could prevent them from flowering so since then I have been opening and shutting the door when the lights switch could that really delay them?

You need no light leaks at all make sure that room or whatever is sealed off any light leaks could set you back a couple weeks ....

wait 5 weeks...report back

I dont think he has a light leak.

I think he has NO LIGHTS!

What are those, two garage work lights?

They arent even the right spectrum for flowering a plant!

Nice big plants, but with those lights your *total* yield will be under an ounce! Spread out among ALL of those plants, too, not per plant.

By the way, leaving watering jugs under the lights next to your plants is an *excellent* place for bugs to chill out and for algae/slime to grow.

How can you fix it? Go buy a 150W HPS combo setup. They are inexpensive. Your plants shouldnt be over 24" tall at the third week of flowering, either. You really should have plants about 1/3 of the size you already have and they still have 6 weeks to grow.

just wait a week i guarantee they'll pop up. it hapened in my first grow they didnt show preflowers until like 2-3 weeks after 12/12 switch

looks like there still in veg to me like u do know the time scheduals dont u

They got too big and they don't fit under those lights. not enough light so they don't have energy for flowering. (plant em outdoors or) invest some time and money in a few cfl bulbs and adapters if you are serious enough to go to the next step, without more light they might never flower
