Will they finish flowering in additional 4~5 weeks?

[Teemo]

Hello everyone,
this is my second post in forum and first marijuana grow. I Want to share some pictures with you and ask few questions.

I've started growing 2 girls indoors in a .6m2, 140cm tall self-made grow box, but when my plants reached my 200W CFL lamp, decided to replace in to bigger pots (12L instead of 5L) and put them in the greenhouse. At that time it was already past 7 weeks (3 weeks in vegetation and 4 weeks in flowering).

Now it's 5 week in greehouse, I;ve fed'em with 9/30/12 fertilizers 3 times a week. Last week I've stopped feeding with fertilizer, and i think they started growing much faster (maybe a root-lock). Now feeding with tap water 2~3 liters per plant everyday. Roots overgrown pots bottom straight in to greenhouse soil. Can;t brought them back indoors, too late

Day time temperatures gets at 22~25C, at night time gets cooler at 10~14C.
Don;t know what exact strain grows, but I'm guessing that it maybe a sativa dominant hybrid..

Will they finish blooming in additional 4~5 weeks? It's already autumn and weather each day gets cooler. Anyone who has more experience with sativa harvest time predictions, or who sees any nutrition problems, please reply. Thank you!

Now it's already 12 week, and here's how they look like.

They look happy to me check underside of leaves carefully where there appears to be a minor pest issue (?).
Five weeks would probably be the very bare minimum finishing time. As for as moving them back inside- I'd probably do it if I was completely set up with suitable lights, etc. Otherwise I would let them do their thing. If you are around to keep an eye on them- it's pretty much guaranteed you'll end up with some bud. Worst case is that it won't be fully mature- but it's safe to say it will make you happy to smoke it.
If you're heading into cool damp weather, them mold/rot will become an issue- possibly a bigger issue than the reduced growth from lower light and temps. Keep an eye out for mold as the buds get larger. Give them lots of airflow. I don't know what area you are in and your climate- but you could check this journal out for a person who's in a similar position.

good job,

Weaselcracker is completly right u have Bugs and the tips of the leafs show little bit over nute.

Dont panic about the weather Fog and Mold ist your biggest problem at the time watch daily.
If the waether getting colder the plant will grow slower but they stopps not completley under 10-7c°

0 ° C - the plant freezes
10 ° C - below the growth stops completely
15 ° C - including the pores close , the metabolism will slow
28 ° C - about growth slows because too much heat must be removed
30 ° C - Photosynthesis ceases
40 ° C - can be tolerated in the short term of the plant , without which they will permanently damage

if the waether too cold u can doe it indoor this is not an problem.

My biggest concern was the cooler temperatures. Thank you guys for your reply's, I'll try to get rid off infested leaves and from now i'm scared of mold : ) I'll post my progression here from time to time, let;s keep in touch. Thank you again.

Leave them where they are doing good , The cooler temps has them bulking up .

my plant is in the same stage of flower, i life in germany.

dont panic about the temps,to avoid mold u can pour early in the morning,if it rain then shake off(touch the stems)to Remove drops, most of them.

a little bit defoilat(Big fan leaves) is good for me, but this is an "believe thing".

I'm in the same boat. I have a 12 week strain and only 8 weeks of flowering weather. Let them go and hope for the best.
A light dose of hydrogen peroxide once in a while will keep the mold at bay.

The leaves with spots definitely look like they have mites, pulling the leaves off won't cure the problem those things will stunt a plant big time if you let them, 5 weeks is like 5 generations to them.
They make products to kill them or you could make your own, neem oil and rosemary are very unpopular amongst the spider mite community.

You could also pack around the pots to keep the roots warm. I use hay on my outdoor veggies in the spring time and it seems to keep the soil a little warmer

hi grimmreefer hi hope we can complete the grows.

Its Autum and i love the stage of flower, they pump up day for day alot more.

To the pest is not mites this is classical thrips,to kill them cut off infect leafs and spray and puor with neem(good nute).

 

[grimmreefer]

This is what a few of mine look like. They need to go until the end of October to really finish. I'm not really good at conversions but I think it gets to be about the same temperature here, tonight it's going to be about 50f.

All that you can do is the preventative maintenance for the mold and hope mother nature is on your side this year

 

[salz]

Nice buds grimmreefer,

my bud only 3/4 of them but we have 12c°night and day time 18c°.

 

[grimmreefer]

So I just did the conversion. It is pretty much the same temperature here. By the time they finish it will be 4-5°c.
Mine also have a long way to go, like four or five more weeks. They should bulk up nicely if they are allowed to.

I guess what I'm getting at is as long as you are careful about the elements they should make it.
