Is this mould on my bud? Many pics

First of all I must let you know that Im planing on harvesting when all the pistils have turned amber & when all the buds are ripe.

My Blueberrys are currently in Week 8 of flowering & the top half of the main cola on one of the plants (top right plant) has become dry & crispy, so much so that when I gave it a little squeeze the very tip snapped off. I must admit I over did it on the nutes, I was feeding it 1000PPM but then accidentally began feeding it 1200PPM Id just like for somebody to confirm if its a case of nute burn,PH burn or if its mould. This is my very first grow so its vital that they are all smokeable.

As you can see the lower half of the main cola still has white pistils I just wondering if ittl spread through out the entire plant or even to the other plant for that matter.


The last 2 pics is the tip that snapped off.

Dos'nt look like mold bt its hard to tell from a pic,

What did u do? cook that top with the light?

I would remove that dead looking top,

The 400w HPS is 14 inches away & all plants are at the same height level so assuming if it is the light burn itll probably burn all the tops.

looks like bud rot to me.... cut that off about an 1" or 2" below the infected area.
remove the dead shit when you see it and it will help you avoid the rot

hows your airlfow in there?

I have a 470m3 inline fan sucking out air from the flowering area. The flowering chamber itself has 4 holes, 2 from the rear of the cab (shownin the pics & 2 from the very bottom of the pics. The rom where the cab is kept has a window always open throught the day & is never shut. I also use Hygrozyme these are some of the reasons why I just cant understand why it could be bud rot. Can this also be caused by nute/PH burn?

Be it budrot or otherwise, you definately have some sort of necrosis overtaking your plant. If i were you i would chop any affected areas and maybe a bit of the surrounding growth as well. I would flush the plant
(if you haven't already) and be diligent in inspecting and make sure it doesn't come back.
Other than that, you're plants are looking real pretty.

Thanks for dropping in. After flushing would you recommend I increase the nute dosage?

To be honest, I would always underfeed rather than overfeed. Doesn't look like your plants have too long before harvest anyhow, I can't really say for sure one way or the other, but i would even consider not feeding again.
But of course the choice lies in your hands.

Thank you for your words, Ill flush for with plain water PH @ 6.2 (which Ive been doing through the entire grow) for 2 weeks.

hey i know what i meant to ask you earlier - whats your humidity in the room?

i had a little bit of bud rot my first run of mtf... sometimes the big burly colas get hit with mold/rot when the rh is high. NOT ALL THE TIME but whe it happens its usually a factor. my opinion.

glad to hear you are checking/adjusting ph ... so many neglect that part.

The humidity is usually between 35-48%

thats a nice rh level....

fucking rot man! such a bummer...

Im gonna cut off the dry area of the bud & a little more just incase. Ill begin flushing from tomorrow for 2 weeks.

I always find a little brown algae stuck on the inside of the reservoir, brown meaning its dead from using the Hygrozyme Im guessing.
But would it be advisable to use the Hygrozyme when flushing, will it affect the taste?

persinally i would flush with plain phd water.

i don't reuse my medium though....

Hey I realized something from the pictures. The other plants look fine around it which is odd and the leaves below that area look fine too, it looks like the area that is affected is right in front of that vent. Is that blowing air in? If so could the air be drying the bud out? I am having similar problems and trying to determine if what im experiencing is rot (my RH is 36-38% though...) or just drying out ?

Here is link to my problem, tell me if it seems simliar...

Those 2 vent that you see in the pics are blowing air into the cab, Ive made sure that the air is not blowing directly onto the buds by rotating the vent (if you look carefully the spacers are aligned at an angle) so the the air blows around the buds & rotate the air around the cab. But then again when I shut the door of the cab the suction increases & theres a good change that some of the air flow comes into contact with that bud.

Judging from your pics the issue seems similar to mine when it first developed, but mine began when I over did it on the nutes, if it gets worse or spreads post more pics & sendme the link.
