I see just a touch of pale green on a few leaves...

What exactly is your concern?
Do you know the strain? Flowering times?
When was the most recent transplant/up-pot?

She looks a little thin if she's only an 8-9 week strain, but I don't really see much of anything going wrong here. :i feel stupid:

IMO it looks totally normal:thumbsup:. It looks like the yellow is starting with the older fan leaves??? Your leaves are going to yellow as the plant comes to the end of its life, its normal. I would just stick it out, it really doesn't look like you have a problem. Did you use nutes and are you still??? If you want to see what your older fan leaves will most likely do, check out my log in my sig...Some won't yellow as bad as the one in my log but it depends on the strain and many other factors too. Yellowing is not always a bad thing:thumbsup:

hi,
thanks for replying so fast,
The thing is i don't know what strain it is, it's just from a seed we found in something we bought, as i mentioned before "she" is in her 5th week of flowering and i guess it will be between 4-7 week until she'll be ready for harvest.

Hi,
I'M using BioBizz nutes. (Bio-Heaven, Bio-Grow, Bio-Bloom, Top-Max)

A few days ago i flushed her with water because i tought she's got a PH problem, and now i'm waiting for the soil to dryout so i can't fert her again.

I am concerned because i saw some amazing growing pictures of plants that are ready to harvest and the fan leaves are still dark green.

another this is that she has full day light from 07:30-17:00 that's 9:30 hrs.
is that a problem?

It could be longer or shorter than that too so dont be suprised if it is. Are you basing harvest on looks or trichomes through a scope???:smokin:

trichomes :thumbsup::thumbsup:
i've got a x100 microscope, and i've checked my :weedpoke: and most of them are milkey white, the rest is clear!

i know it could take up to 7 weeks, i've got time, no hurry!

b.t.w, DogtowN mentioned that she looks a little bit thin for 5 weeks of
flowering, and i guess i tend to agree, is that because of the strain?
or am i doing something wrong? does the fact that she has only apprx. 10hrs of light and it's like 13C degrees at night, are these parameters affect the yield?

I cannot really judge the size of your plant based on pictures, sory. The light and temperature could very well cause an issue with the yield. What are the temps like during the day?

As for your trichome development, that is good that you are using the microscope. Are you looking to get a certain high out of the smoke, like couch-lock or more cerebral and energetic???

The plant is linke 72cm high, i pruned it once at about 3 weeks of grow,
There is a clear day light, without clouds, apprx. 19-22C, direct sub light from 08:00-16:00.
Regarding to the smoking affect, i'm looking for HeadHigh, don't like the couchlock affect, too much for me :jointsmile:

If you're looking for the head-high then you're going to want to harvest when the trichomes are all to mostly cloudy. When amber trichomes start to develop and show, that means THC is degrading and the couchlock affect starts to take place.

Cloudy Trichomes=Head high
Amber Trichomes=Couchlock

it seems like i've been wrong about the flowering time :wtf:
i've attached 3 photo's that were taken at 9.12.2010,
and she's already been flowering, which means that she started flowering
at about 5.12.2010? and that means i'm in the 7th week of flowering:cool:
So, i've got no freaking clue what that means and how that effects our discussion:jointsmile:

i think i'm gonna chop her in two weeks time.

I think you've got a pretty good handle on things.
10 hours of direct sun is nice! IMO the low temps are the main issue with it looking "thin". A container plants roots get pretty cold outdoors, colder than if it's in the ground. It slows them down a lot because they have to warm up for all those little soil microbes to get up to speed again.

You've done a good job! Not knowing the strain is a huge wild-card.

As long as you use your scope, you'll get it right. :thumbsup:

Thanks dude!!!
This is most appreciated!:thumbsup::thumbsup:

i don't know the strain because it is from something we've smoked along time ago...
