4th week of flower funny smell

[Blimsa]

I have googled this and not come up with anything conclusive other than plant stress.

After a week of very warm weather, this little auto looked to have taken it on the chin, however recently the nice smell has faded and been replaced with a chemically smell (not sure it's the exact smell of ammonia, my sense of smell isn't great).

Leaves look ok, don't think there is any mould as don't think it's been overwatered. No sign of bud rot or any visual damage. Leaves still have a bit of the normal scent, and soil smells fine.

I have given just plain ph'd water the last two feeds and run off is 6. Not got access to ppm tester.

Anyone have any experience with something similar?

I'm waiting to see an answer cuz same thing thappens to me. When i touch the bud, nice citrus smell, but when i smell without touching it its a mix of seaweed and amoniac smell. Entering fourth week of flowering tonigh

Ammonia smell is usually an indicator of bud rot
A stong Ammonia smell that is.
I getta whiff of a slight "Ammonia" sometimes myself, usually if I smell my carbon filter exhaust.
More than likely you're just smelling the effects of a dense bud
If there's no visible signs of bud rot... you're good
Be sure to have good airflow
An oscillating fan
A regular fan
Something.

Thanks firts time growing here. 21 days of flowering there is no sign of rot for now. Buds are still developping and tiny.

With the wind today there is aromas of citrus. Seems to be ok but when i just smell near a budsite, the odors is strong and not well defined

Those are looking pretty good.
The smell and levels of smell change throughout the weeks.
You’ll notice that dank mj smell really good during the last few weeks.
That’s when you know it’s getting close

mine don't stink until the last couple weeks.

You can smell them but they aren't wafting if you know what I mean.

Touch them though and you will smell like good ass weed.

For a first time, that is a very lovely canopy! Well done
Do you know what strain you are working with?

Bagseed from lemon thai kush, they said more sativa than indica, but leaves are more indica. And i started them may 21st. So i dont know what they will look like at the end.
