Plant wont flower

hello im not new to growing but i have a slight problem. i have 2 plants, 1 is a sprout the other is a month and a half old it is more then 12" high and on like its 9th or 10th node. its been on 12/12 since seed and its still not flowering!

my room is lightproof i hang a blanket over the door just to be sure. i feed it with superbloom fertilizer to try to force it but it still not flowering. is there anything else i can do or do i just have to wait.

should i put my lights off longer?

A plant needs 12 hours of darkness to flower (except autoflowering strains). So if you want flower I would not recommend a longer light cycle and doubt that more dark hours will do any good.

What strain are you using? Is it a fem seed?

I have never done 12/12 from seed but wondering if you know the sex of your plants? Any preflowers yet?

Reeny, He said it was 12/12...

Quest, If your plants are on 12/12 from seed and there are NO light leaks durig the dark cycle then I would say your plants are not mature yet if they havent started preflowering. Some plants mature later than others, and no MJ plant will flower before it is old enough. I would give them another month before you really start to worry.

Look at it as a good sign since males alomst always show sex first and flower first. And nobody wants males! (exept for breeders of coarse).

Good luck

top it and wait a couple days that is what i had to do i had mine in flower for 3 weeks no signs until i topped it then bam busted all her girly parts out

thanks for the reply guys, the strain is bagseed. mexican brickweed i assum. it was some really decent smoke though. ive top the plant already like you said. its been topped for about 2 days now. im not sure if i can see preflowers or not. i looked at some of the side shoots and it almost looks like hairs are showing but i cant tell for sure. it could be just a new shoot growing or a leaf or something.

i did 12/12 from seed on my last grow and i had 4 or 5 plants and got 2 females to flower just fine but it was in a different closet. i dont see any diffence in my new closet its the same as the last. ill wait till the end of this month and hope for a female. its really starting to stretch bad since the light is at 12/12. the second plant, the sprout, is on like is 3 or 4th node and doing really good. its a really dark green color with brownish/red on the leaf stems. i have a cam but this new windows vista wont let me download my pix from my cam to the cpu for some stupid reason only videos from the cam. so i dont have any pix.

lol absolutely completely, iv never seen those words used right after one another. thought it was quite lyrical. but anyways don't worry if it hasnt showed sex yet. Just make sure there is no seepage from light and it WILL show sex. Things you CAN do to encourage your plant to flower is feed it fertilizer that is high in phosphoros low in nitrogen and moderate to high in potassium. Also make sure the lights you are using are 2700K Spectrum which is warm white. Warm white is the best spectrum light to use during the flowering stage. be patient and it will show sex. keep up the good work my man.

I am not saying that you are wrong, and even if I really thought so I would be hesitant to be so blatant as to flat out say it since that is rude plus it is not like I know everything but I have to be a bit curious if you are really correct or if there are just some strains/hybrids that mature very early or that do not need to actually mature much to flower.

The reason I am curious is a few years ago I was going to start in indoor grow so I tried to pop some beans and while they usually pop for me in around 12 to 24 hours after about 48 hours or so there was no sign of any of them doing anything. The nest day I looked and there was still nothing so I decided to try some other beans but figured I would just leave the first ones and see if anything ever happened or not and maybe found out if I just got a pack of bad beans.

The second batch popped in the usual 12 to 24 timeframe and soon I had them in the soil. I sort of forgot about the other beans and a few days later looked at them and they had a very tiny bit of white beginning to stick through the shell. I decided to wait and see what happened and sure enough they all popped but they just took forever for some reason.

I did not have room for them inside and it was already well into the summer and figured that it was to late to grow them outdoors but I thought what the heck, I’ll give it a try and if I get something it will be a bonus and if I don’t I haven’t lost anything more than if I just toss them so I planted them in large pots on my deck.

It was only about 3 or 4 weeks to the summer solstice and when the days turned to 12/12 and then less the small hardly vegged plants showed their sex and I yanked the males and the females grew and flowered and while they were small plants I still got buds of a decent size, not a bunch of them due to the plants sizes, but I got buds and the plants got very frosty and the pot turned out to be great.

The beans were supposed to be a G-13 X White Rhino cross. I have always been somewhat dubious of anyone who claimed to have G-13 but the beans were given to me so it is not like I paid a bunch for something they likely were not so it didn’t matter to me what they really were. Well I hoped the White Rhino part was at least correct and as frosty as they became I tend to think that part was correct.

But there is a case of plants that should not have been mature still budding and considering their small size due to a late start still producing half decent and giving a darn good buzz.

So I am just curious if there are exceptions to the rule or if you think that cross might have fallen into where you said some plants mature sooner and that particular cross could mature that quickly or if maybe plants do not have to really mature but at least only have to reach a half mature age to be able to flower?

Frankly I was very surprised how things went and it made me wonder if what I always believed, which is what you said, was really true or not or if there are exceptions and if so if they may even be partially based on conditions or if it is strictly certain strains/crosses/hybrids or what?

its true a plant wont flower b4 sexually mature... all aspects of all strains are diffrnt some mature at 3 weeks some mature at 7.. just like some take 60 days to finish some take 80

if it takes a while they say its going to be female and mine did!!!

the plant is showing hairs on the very top but it is going on 2 months now and still no preflowers. whats going on here?????

here is the small sprout that is growing in the same pot. yah i know you're not supposed to grow 2 in the same pot but it came up way later and i just left it in

Eventually they will really fight each other for space. Both canopy space and root space. Maybe one will be a male so it can get chopped. If it isn't then you will have to pot in a larger pot and tie both the plants in opposit direction for even canopy coverage.

They are looking really healthy and green. You should get some pre-flowers very soon.

Also, what feeding reg. are you using. Your plants look healthy but maybe they could use a dab of N, allong with the flowering ferts of coarse. Could be the lght aking them look lite green.

But agian, they look great and you seem to be doing a bang up job. +rep

put em under 12/12 lighting

They already are man. Since seed.

the hairs are the preflower.

i checked it today and it has ALOT

I checked it today and it has ALOT more hairs covering the top of the plant so I think it will be fine. Im feeding it shults super bloom its like 10-59-10 npk i think. I have some fert with more n but i think the superbloom has enough to keep it vegging while flowering. i dont know what im going to do about 2 plants in 1 pot. the sprout looks like it stretch an inch in 1 day. im just going to let them both grow untill a problem with space comes then ill deal with it then. thanks for the replys guys
