WTF IS WRONG WITH MY PLANT NOW!

So its in probably 2nd week of flowering. its an autoflower i thought it was growing pretty nice i started the budding nutrients, i have only fed nutrients once to them tho. the bottom half of the plant some leaves are turning yellowish with brown on them. just pretty much dying! i havent changed anything since they were little except the nutrients a few days ago. htis morning i woke up to some of the leaves just fallen off! i read that some strains do that but i think in m case it looks severe considering there are barely any buds yet. any help?

It's harder to diagnose spent fan leaves in flowering. It could be that she exhausted the nutrients in her pot and your feedings haven't kept up with her needs. It could be that you don't a have sufficient cal/mag. Some plants just pull nutrients from the lower leaves faster than others do. I would be curious to know the ppms on your run off or the ppms of your feedings.

Hard to tell with the HPS on in those pics.
Try another set with natural lighting and the HPS off.

Plz Help im starting my second week and i think i have the same problem they look healthy but i see a lil red in the stem and the top is fine just the bottom leaves sometime shrivels and dies

I feel like it's gettin worse everyday and there is really not anybuds comin yet

do you have purple stems??? or no
cause it look like a potassium def and what ph and ppm are u running

autos should start budding right away even under an 18 6 light cycle. i see you dont have much perlite in your soil. What kind is it and what are you feeding them?what is your ph soil and water?

My autos stay looking ugly until the last two weeks if that helps.
