High ganzigunnu,
I am 100% sure that this is a calcium dificiency. The cause of this deficiency could be pH issues or overfeeding. They both cause nutrient lockout but it doesn't really matter what the cause is.
But it does matter that you can fix both of these problems with a good flush of your soil and I will explain you how you can do that the best.
You can do this flushing by slowly pour water pH 6.2 onto the top of the soil, allowing it to drain freely from the bottom of the pot. Pour slowly, so the water doesn't overflow from the top of the pot. Use approximately four times the pot's volume in water to flush the soil. For example, use 1 gallon of water for a 1 quart pot.
After the flushing you need to let the soil (almost) dry out completely.
From there you can start giving water with pH 6.2 and nutrients but do not exceed EC 1.8 to make sure that you don't overfeed them in their last weeks working hard making those buds bigger, fatter and juicy!
Happy Growing! 😋

Feels like a PH issue to me, but natural fading/lockout could also be it. your EC is quite high for an autoflower grow to me.
I try and keep it in line with these numbers

Your very close to be done and this would not affect your end yields by mush is anything at all.
I would keep up what your doing and lower your feeding solutions EC like down to 0.5
Best Of Luck & Happy Growing!

heh, first guess was gonna be light.
pH proper?
At this age, senescence is a possibility too... simply the plant nearing end of life and drawing down leaves.
it's chlorosis and at the top (immobile) with some bronzing
it'd be rare but are you watering with something that has large amounts of chlorine in it? maybe, excess iron? Boron deficiency? the thing with these trace elements is that they are very rare in soil and more indicative of a pH issue.

I think your ladies are saying it's beginning to die naturally... and that you should prepare for your time in trim jail... Have you taken a close look at the trichs? This will give added information on which to base your decision of when to chop them... But seriously, everything looks fine with the conditions you're providing - and, being autos, they're about at the end of their lives...
Good luck!

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

I believe I fixed my nute lockout a couple of weeks ago. But since flowering has started I’ve been getting a deficiency on the older leaves from the bottom moving to the top. I’m wondering if this is A nitrogen deficiency as I’ve backed off on the nitrogen since I’ve switched to flowering nutes. I’m not really sure how to proceed or if I’m even right.Week 21
