Problem

is this nut burn?

That kind of looks like a hermaphrodite plant to me... I'm not 100% but those look like nanners or pollen sacks all over. Wait until someone else confirms this though, I am not an expert. The reeeaaally strange thing though is that they are purple/ almost brown looking pollen sacks.
Either this is an incredibly uniquely colored strain, or you got something fucked up here. I've never seen any sort of nute burn like that. The purple stems can be a potassium or calmag deficiency, but often times that is just the strain.
Wish I could be of more help.

that doesnt look good i agree looks hermie. but looks not happy either

but seriously give all the info you can about the plant

just throwing up a photo saying whats wrong isnt helpful to us and unhelpful to you

You fed it bloom nutes yet?
Soil?
Nutes? What kind and how much?
Water? How often and what kind? Does it have a softener on the water? Kind of looks like salt poisoning.

Soil? What kind?

Light?

Temps?

Humidity?

It's outdoor . Midnight/blue knight strain kinda auto flower . Purple stems it's like that the top bud is ok . Inside and bottom look like the pic ..

Yes been feeding monster bloom and chi Ching .

I don't think it's Hermie I can tell is it is

First pic looks hermie, second pic does not. But that second pic is multiple plants. Are you sure one plant hasn't just gone rogue on you?

Well if it has revegged that is important to say! That is probably just old flower then. The stuff that grows in flower, then reveges is unlikely to survive. That may be what's dying

Thanks for the reply some more info for me to figure it out

There is nothing to worry about, if they are just dead old revegged flower. Just pick them off as they die. It makes sense that it is happening at the bottom of the plant where the old flowers would have been. The rest of your plant looks great.
