Couple plants 21 days into flower, hardly showing bud/brown spots.

So i flipped to 12/12 21 days ago now, yes i had to switch them when they were quite small (20 day veg) because i'm shifting houses.
My other thread with older photos etc.
https://www.rollitup.org/marijuana-plant-problems/648885-first-time-grower-1-out.html

Little concerned about the lack of buds forming etc, they are both female plants, wee plant is going to be scrapped.
Also a few brown spots on some of the leaves on the right hand plant, as well as bottom leaves kinda yellowing/dying !
Think i'll have to tie the left plant down cause its getting too high for my box.

Any other concerns i haven't seen? As this is a first time grow.

They don't seem right to me....tell us more about your set up, temps, air exchange, etc. These are pics of some of my current plants @ 24 days 12/12 also under a 400w HPS and in a homemade organic soil mix:

Typically, I have only seen leaves curl down that much twice. One was an outdoor grow during extremely high temperatures. The other was when we tried DWC and had bit of root rot.

This does not mean that this is what is going on, but to me they don't look very happy.

I know, they seem a bit off to me too, but i have nothing to compare cause its my first grow.
Just lately temps/rh have been weird cause we just hit winter and we've had shit temps/rain.
Growing indoors under a 400w Hps, Temperature is between 45-59 Fahrenheit lights off, i can keep it at 59 Fahrenheit with a heater and Sits around 68-77 with lights on.
Have 1 intake fan and 1 exhaust fan, both 80mm computer fans, and 2 random passive intakes.
Feeding organic nutes.

I agree they're not looking quite right. Your temps seem a little low, which could contribute to slow growth. Try to hit 80 with lights on and 65-70 with lights off. Also, what about light leaks???? Looking at the plant, it seems they don't know they're on 12/12, so maybe they're not, even if you think they are. Alicakes' pics are more typical of a plant that is responding to 12/12.

Yeah, i agree about the low temps, i'll try get them up a bit.
I'm 98% positive there are no light leaks.
They're on a timer that i've set to turn on at 7pm and off at 7am, unless thats faulty i don't know how to test whether they are or not.
They are budding up a wee bit, but they seem to be quite slow.. I will check light leaks today and will try get the temperatures up a bit.

Cannabis will NOT automatically start to bud just because you switched the lights to 12/12 IF they are not sexually mature... they have to go thru a complete chemical change (kinda like puberty) when you switch the lights, and if they are too young, you have to wait for that chemical change to happen before they start to bud.

the "days until harvest" set by the breeders (eg: 55-65 days) means from the day they start to bud, NOT from the day you switch the lights... so as soon as they started to bloom after you put them 12/12, use THAT as day 1 of the 55-65 days until harvest!
They look to be in about week 2....?? ;)

it could be a mix of low temps and nute def ? hps lighting is so hard to make out what colour the leaves are . but to me it looks like they are budding at the top .

were they mature when you flipped ?

Thats good to know, thankyou. They were only 20 odd days vegged and i have been switched to 12/12 for about 21-22 days now, So yes probably about week 2 from when i seen change.
There are no light leaks and the timer seems to be working fine as i check them when the timer turns on and when it turns off :)
Yes, the tops are kind of pre flowering, there are pistils etc forming.
One of them is Northern Lights X big bud and the other is Kerala x skunk#1 which was a free seed.
They weren't mature when i flipped being only 20 days into veg!
I seem to not have to water for ages.. like over a week before the top even starts to dry because the weathers so shit?

I do hydro, so I can't help on the weather/soil/watering point. They were very young when you flipped, but now they're about 6 weeks old in total, right? Are you seeing alternating nodes at all?

I think you're going to be okay...they just need more time.

Yes, thats right.. Around 6 weeks now all up.

I just went and looked for alternating nodes but couldn't see any.. :(
Although i don't really know what i'm exactly looking for.

Edit: Definitely none on the main stem, could be some on the branches off the main stems but i couldn't see any with a quick look.. as the lights are off at the moment so hard to see.

yeah temps that low won't help with watering. you have low amounts of transpiration from the leaves which is essentially the reason they're not going to grow as fast. they can only grow as fast as they uptake water and nutes and transpiration is the main driver for that. for future reference, as long as you have good air movement and ventilation your plants can respond well to temps as high as high 80's to 90F (strain dependent) during veg.

now you really don't want temps that high during flowering, you are sittin pretty with the temps you're at (60 lights off 75 lights on) in fact some growers will seek out lower temps as it can help some purple strains with the color change. imo your grow will start looking up soon if you can correct whatever is making your plants look claw/spotty- maybe pH/ nute issues? how close to the light are the tops of your plants?

Thats good to hear thankyou.

I feed with 6.3-6.5ph water but my run off water i test after i feed is always low.. like 5.0-6.0, got told not to worry about it that much as they seemed to be doing fine.
Only one plant has that claw shit going on which i think is because its not drying out?
I don't know what the brown spots and clawing is or how to fix it..
The 400w HPS is about 30-40cm from the top of the left plant, i will have to tie that plant down i think because its getting too tall for my grow box?

Few close up pictures of the right hand side plant, the other plant has no spots and bugger all curling.
Whats the problem with this plant?
The yellow leave photo is a picture of the very bottom of the plant.

yeah man if it's not drying out enough between waterings you can get quite a few different problems. overwatering will cause the claw look a lot of times......the spots look like a nute issue to me (admittedly i'm not the most versed in these, you may want a second opinion) what kind of nutes/ what doses/ how often are you giving them?

these may help as well, they saved my plants more times than i care to admit when i was starting out. good luck :joint:

edit: i didn't realize how little 30cm was because i'm american (fuckin 'standard' system, derp) you might be stressing your girls a bit....i think a 400 watt should be more like 50-60cm at least from your tops (again, not the best source here. i typically use 150/250 watts)

Thanks for the info bud, i up'd the temperatures a wee bit to try make them dry out between watering.
Yeah i think they're meant to be more like 40-50cm so will fix that up a tad.
