new grower why arent my plants flowering ? its been 1 month on 12/12 lighting 600 watt hps bulb

only 1 of all these plants has hairs that are noticeable here are some photos please help, if u have any knowledge to help me out

these are all female plants a mix between ( dr kripling incredible bulk, dr kripling bud bud tingz , and white widow big bud) started from seed has been 1 month in to 12/12 only 1 plant has clear signs of bud as seen in the photo the rest not really much going on why is that any help please, im thinking i need another light and a intake fan ? as i only have a outtake fan runing atm ??

Any light leaks? How old were they when you put them into flower?

2months old in veg then i put then into flower very small light leaks possible its in a tin shed ive tryed to cover up light leaks with panda sheet and gap filler so hardly if any light gaps

im thinking maybe its becuase i have no intake fan so theres no new air being brang in ? just air being sucked out by the outake fan? ?

I see tops budding just slightly slower than it should be.

good to know will thay all catch up ?

the air flow shouldn't have anything to do with budding, besides the general health of the plant. you need to go into the shed at night and see if there are any leaks, after 4 weeks of 12/12 you should definitely have something going on

Where did you get the plants? Were they seeds or clones? Maybe someone pulled the old switch a roo and gave you sativa seeds. I know mexican brick weed is sometimes tropical flowering sativa so when you try to grow them inside they take like 4+ months to flower. I'm thinking you either have some tropical sativas going or somebody/something is interrupting your dark cycle.

If plants were at like week one of flower and something interrupted a dark cycle it could set back you flower a week making it look like no progress.

Those are my only thoughts either sativas or interrupted dark cycle. Poor ventilation will only slow growth not stop flowering from happening.

I see the bud on top starting to grow as well. Maybe just a slow strain? Are you using nuits at all?

Im going throw it in there probably nutrients. Even if light leak still would flower and i have seen plants flower with poor ventilation. My .02

I'm pretty surprised how good there doing other than the flowering issue I mean u got 6 plants under only 600 watts and they look super healthy and happy I'm going to put my money on a slight light leak and maybe a slow starting sativa but hey what do I know lol I am always learning no matter what that's part of the obsession with growing

light leaks will not keep a plant from flowering, unless maybe you have a hole the size of a door.

What are your night temps?
How far away is your light from the tops of your plants?
Have you adjusted your NPK ratios to compensate for flowering?
Are your pots sat on a concrete floor?

That's what my plants looked like when I didn't add nuits to be honest. The growth rate was much slower compared to using nuits so if aren't using any, I'd say your plants are on schedule.

I see pistils in all the pics.

Some strains are slow to start.

As stated earlier, the more sativa the longer for flower to set in. Landrace strains like Mexican brick seeds can take 4-5 weeks of 12/12 to show sex. Some longer.

Many pure sativas are equatorial and get near 12/12 all year and will take a lot longer to flower.

I had a buddy who grew in his basement but was to lazy to block out the little bit of sun light that came in from the window in the next room, after about three months he had about one bowl of whispy ass bud. So technically yes the plant will flower but not much better than OP's plants.

The slow flower has nothing to do with nutrients.
