advice needed please

[moxxorax]

can someone please advise me....
i have been growing 5 plants for 9 weeks and 2 days and 1/3rd of the flowers have turned amber brown and the flowers have started to droop a little. They are a little sticky and are showing good signes of THC production
is this normal for this time period.
My last grow took 12 ish weeks to complete so i feel these are a little early.
any advice is greatfuly recieved.
some pics. sorry but they are not very good

Are your plants 9 weeks from SEED or from the time you started 12/12 light schedule? And what strain is it? The flower time should be listed by the vendor you bought the seeds from.
Premature ripening combined with droop and paleness are symptoms of too-hot conditions... I don't see your pics though so no real help, sorry...

9 weeks from date of plant or 9 weeks from first day of flowering?
These seeds or clones?

Different strains finish at different times; are you growing the same strain as last time?
INdicas the ones with fat leaves tend to finish faster where sativas .. the ones with skinny long leaves take longer.. so when you have a mixture of them it can be in the middle 45 to 65 days depending on the % of sativa and indica.

Are you using a microscope to look at the trichcomes on the leaves?
9 weeks is pretty long sounds like you have a more sativish strain....
You can use a microscope to look at the trichomes on the leaves; you want to take a look at the heads of them; you will see either clear, cloudy and amber ones for the stage you are in.

You want to harvest when most of them are cloudy and amber; depending on the high you want.
Couch lock or head high
cloudy and amber give you both
clear ones will give you nothing; but there is no way you can harvest with all trichs cloudy or amber; there will always be some clear; but you want to harvest when you see very little clear ones.

You get a 20X or 30X microscope with a light and take a leaf and use the microscope to examine the heads of the trichomes; you will see the colors on there.
Can you post pics you have?
Do you know the strain?
Flowers drooping does not sound good..... pics would help out a lot; also checking the trichomes would be too.

thanks for the speedy replys.
the seeds are white widows taken from my last crop that went hermie.
they are 9 weeks and 2 days from seedlings.
i have them in a wardrobe setup under 400 HPS with a fan blowing air around the plants.
if this is heat stress will it affect the outcome ?
thanks in advance

 

[moxxorax]

the trichs are still clear but the flowers are turning brown to amber in color. i dont think its a heat problem.
i am using vitalink bloom and buddie.
buddie at .5 ml per ltr every watering and bloom was used every other at 2mls per ltr. i have stopped using the nutes now.
i will try to post more clearer pics soon.

 

[MynameStitch]

Pics say thousand words. Yes, heat stress reduces yeild and can cause plants transpire quicker which you do not want.

Buds will turn brown and plants can be droopy from heat.
How hot is it in your grow room with lights on and off?

 

[moxxorax]

The lamp is about 10 inches from the plant tops and the temp in the wardrobe is around 20 c.. cant tell for sure as my temp guage smashed last week. The plants are not drooping, its just the flowers and buds that are turning amber. The doors are left open when lights are on and then closed for the dark period when cooled down.
The plants have lots of buds and they are producing THC , but they are not very sticky at the moment. Will they produce more thc in the next week or two.

 

[moxxorax]

Can i just add that the flowers are turning brown to amber all over the plants, not just near the tops.

 

[MynameStitch]

Depends; without pictures on this matter would be hard to tell; because normally they brown the older pistils do.... so deciding when to harvest by the pistils changing colors is bad idea imo.
I always go by the trichs.

 

[moxxorax]

check out my gallery for pics mynamestitch

 

[MynameStitch]

Can you upload pics that are not blurry? Also take them with the HPS Not being on; it's way to hard to tell with that on.

But from the pics it looks like normal pistil's dying; you wil always have some dying. You can't go by them when to harvest; like I said in my previous post in this thread;you need to get a microscope and check the heads of the trichomes; there color on the heads will tell you how much longer you have to go.

 

[Guest]

i would be willing to bet you got a hermie from your hermie and the hairs are dying because she nutted on herself...have you checked for pollen sacks or for yellow dust

 

[moxxorax]

i have checked daily for hermie sacks and as yet found nothing. i will be getting a mag this week so i can check the trichs.
what do you meen by "nutted on herself " brainthor

 

[Guest]

i mean the same as her mother did in the last grow lol pollinated herself

 

[moxxorax]

as yet they are showing no sign of hermi sacks and they look fine for 9.5 weeks. the leaves are yellowing though and this is concerning me. i just hope they go the distance. need to check the trichs.

 

[MynameStitch]

I have grown out hermie seeds before; they are not stable so it depends on the plant and the environment if the plant is going to go hermie again.....

So because you have hermie seeds does not mean it will hermie; but the chances are a lot higher that it will, even in pristine condition; so it's like a slot machine really.
You hit them with the wrong kind of stress, it may hermie in some areas of the plant.

 

[moxxorax]

thanks stitch
no sign today of any hermie sacks but i will keep looking. my main concern is the color of the leaves on one plant and i fear the other four are going the same way. i have added a shot of the worst affected and have more in my gallery. please feel free to gaze over them at your leasure.
After looking through the faq my thoughts are that it may be Magnesium deficiencie but i am new at growing and need some advice. The plants are just 10 weeks from seed and have been grown under 400 HPS in a wardrobe setup. I have been feeding with vitalink buddie and bloom.

stinkyattic asked you...Are your plants 9 weeks from SEED or from the time you started 12/12 light schedule?

And you never really fully answered that question, except to say this...

they are 9 weeks and 2 days from seedlings.

I know this question may sound wierd, but is that now ten weeks all 12/12 and zero veg time ?

 

[moxxorax]

sorry, what i meant was they are now 10 weeks from when the plants were just showing through the soil and veg time was four weeks.

 

[10k]

So these have been in 12/12 now for six weeks total ?

I wouldnt worry about the yellowing at this point.
Its quite natural to begin yellowing the big old fans about now.
Think of it this way, the plant is just getting a head start on the final clearing & finish.

I do hope you've got some decent airflow in that closet during the dark hours, or you'll be looking at possible bud rot soon from all the overnight transpired moisture closed up in that closet all night.
