too far gone????

I think my biggest bitch is to far gone I tried pretty much everything that I felt was helpful from the first post but nothing seems to b working
the leaf tips are burnt and curling upward I think she's threw let me no if its even worth my time

thats ok man just add a top soil of organic N based soil, then water it in. yellowing fan leaves late in flower is a sign that it is out of nitrogen. If you plan to harvest in the next week or two i wouldnt even add the nitrogen id just let it go. Your soil does look very heavy look into good soil mix ratios. lots of growers use 50% perlite because they like watering every 2-4 days.

Looks no where near done? If not get a good nitrogen nute feed and feed her.

From your other thread, did you ever say what kind of soil you were using after I said it looked like shovelfuls of DIRT from the yard, with rocks, clumps and shit in it?
That stuff looks pretty wet, IDK same pic or not, but do you have drain holes in bottom of bucket?
