URGENT HELP!!

Did you flush it after you stopped feeding? Or did you just stop feeding it? - If you fed it too much, it'll take a while for the plant to go through what's already been put in the soil, and you'll continue seeing damage until the excess nutrients are gone.

It is an amnesia haze, so 9-11 weeks flowering time and only in week 6!

I don't see much of an issue.. It's the end of its life, It's desperate to get pollinated, so it's just letting the leaves die off slowly, as it's using the nutrients to produce tricomes to catch pollen in the air. Should be ready to harvest in a couple of weeks.

the plant is nearing its end, start your flush with just water for the next few weeks, she getting close
