Hi folks just wanting a few opinions on whether this is bud rot or not? My plant is suffering with a suspected lsf problem anyway and Im not sure whether
this browning of the bud leaves is lsf, rot or something else! Week 8 of 12/12 today, temps are 20 lights off 26-28 lights on and just switched to plain
water this morning from 1 ml/l bloom last feed. It is this bud in particular which looks worst affected..




Link to my diary in my sig, really appreciate your opinions/advice

it dosent look like budrot, it just looks like normal light bleaching of the leaves at this late stage of flower, i get this with the buds that have been too close to the light.
have you checked for rot deep inside the bud, i check by gently bending the bud open to look deeper inside, if you see brown furry stuff, then you know its rot.
what is the humidity, did you get a meter?

Difficult to say for sure without seeing deeper into the side of the buds

But I'd say no, it doesn't look like budrot to me - if it was budrot the affected leaves would have wilted a little more and you'd be able to see the furry aerial mycelia of the rot/fungus.

A good indication is to tug on the leaves that you suspect have been affected... if the easily come-away from the stem in your hand then it's a good idea to have a closer look.

Put 'budrot' into Google images and you'll see some lovely pics of the real thing...

Hope you pin-it down... and I hope it doesn't turn-out to be budrot

looks like vit deficiency ..the first sign of bud rot can be detected early if you check the leaves coming out of the bud..if there is rot in the flower the bud leaves will droop and can be pulled off easily...the rot starts at the base of the leaf.I think yours is a nutrient problem,could be lock out ?

I've posted on thish in yer diary man, .... yeah

I hope you don't mind me posting an abridged version of your reply here, Mr Layne. It's just I thought it was useful information and worth copying

Bud rot! Where? I can see why you might think it, but unless I've missed it - I cannae see it, cap'n! To be sure, just hold the stem firm and tug on a leaflet tip, if it comes easy off the bud, look more carefully for grey mush. If it resists and wants to stay on the bud, pour yersen a beer, roll a lardie spliff and chill big style!

And yup, I'd be taking off the damaged leafs, those that will come off, that is.

@Worm Thanks mate I had though about light bleaching, the light is around 10 - 12 inch away from the tops and it passes the back of hand test so I presumed it must be something else, I did get a meter yes humidity is yoyoing between 45/60 percent. I have looked closely for signs of mold in the buds bud havent seen anything other than these browning leaves.

@Stan909 Cheers buddy when I remove the brown leaves they are extremely dry and crumble between my fingers. I have done a google search and havent been able to see any of the fluffy type rot that comes up just the dead leaves which I thought could be an early sign

@Iky I have had nutrient deficiencys and lock out throughout as a result of having too low temps at night, But I thought I had it sorted when I added another tube heater to stabalise night temps, but maybe the damage done was too much to recover from?

Cheers everyone I'll have another close look tomorrow

I let some JACK 47 get attacked by ROT as an example to show folk who have never seen it.



As you can see below, the camera refused to focus on the muck.

You will know it by following the advice given. Foul muck it is. Some say that you can use it. Not for me.

Hi Hiphop good man for sacrificing nice bud for the good of other growers, looks nasty stuff that must be heartbreaking to have that destroy a crop.

It didn't ruin the whole crop mate, i was aware that there could be issues and saved about 80% of the grow. The Tai's were the worst. But, a few folk commented that they had never seen it so I gave them an illustration. Below is the TOTAL lost from this plant.



And a bud removed from a TAI.



I have had experience before with the stuff mate, so I know that SWIFT ACTION often results in a saved grow, even 50% is better than nothin. It is important to check the top third of any dense resin filled buds during weeks 7 to 9. Be aware of the possibility and you should be fine.

Thanks for reading.
