Black mildew type leaf infection

[nicelytoasted123]

Hi everyone!

 

One of my ladies has developed a black mildewy looking leaf infection. Can anyone tell me what it is and what causes it?

I might just harvest it tonight it's pretty close.

I just don't want it affecting the other plant which is about 5 weeks behind.

Doesn't look like mould to me, although pics sometimes don't show up clearly. The mould I had a couple of seasons ago was in the buds, that is usually where it starts in outdoor grows, as the buds hold the most moisture.

 

You will find that a small fan leaf will start to die off and turn dark to light grey. I just cut the whole cola off as imo it is not worth trying to cut out the mould as it only helps it spread.

 

But yours does not look like mould to me. Maybe a nute deficiency getting so close to finish. Keep your eye on it though.

G'day Brick! Could well be. I haven't fed her for a week. It's near the end so I'm just giving a little water every few days. This doesn't look normal though, it can be rubbed off with your finger.

Could be powdery mildew. There are threads on mould and mildew probs in here. I remember radic had a good answer to solving it, I have used baking soda lightly dusted but radic said there are a few different types and some are better than others or less healthy for you than others.

Thanks as I said I might pull it tonight anyway. I'll have to keep an eye on the other one though. I thought powdery mildew was white? At least there's none on the flowers that I can see.

ill give you my ges 't it might be some desese , if it starts spreading down the leaf stems cut them off before it gets to the main stem ,

but i think it just wants abit food , dont worry bricks rite

never had anything to do with mould but the rubing off dont sound good

Thanks mate, that looks like it. I didn't take any chances and cut it down last night. Some mould had started in the centre on the main Khola but fortunately didn't lose much. I'll keep an eye on it.
