8 weeks Flower all leaves dry yellow and going crispy

im just about to hit 8 weeks flower - at 3 weeks flower my leaves started yellowing and going crispy and dying and been going eversince . all leaves at this point (whats left) now (8 wks) are dry crispy and can easily be snapped including new small leaves that form at the tops. buds seem fine although very thin and airy not dense
wether they fill out these last 2 weeks i dont know as this is my first ever grow and the strain is 9 - 11 weeks

BLZ Bud
Soil - perlite
Temp - day - 24 C night - 21 - 20 C
Biobizz grow and bloom
ive also added epsom salts on a few feeds

my question is.....

is my plant ok to carry on in its state ? im waiting for 50 cloudy 50 amber trichomes, so far its around 50 clear 50 cloudy

Ill try to add a photo

if it has no leaves left it will struggle to make energy to grow, depends how bad we are talking but it sounds like the girl is not going to put out perfect meds no matter what you do. probably best to chop her and start again.

any pics?

yeh man - ive been trying to upload photos for the last hour !!! if i keep trying, im afraid i wont have a computer soon as ill be swinging it out my window.
anyway i still have some green leaf about but its all dry and could snapp if i bent them....... id rather not cut now as id like to see at least some amber trichomes before i do ?

Is my plant still producing with almost all leaves dead ?

really need a photo to help.. how come you can't UL a photo, is it giving u a error or what?

99.9% sure you have/had too much P by high P bloom foods.
You describe P toxicity to a "T".....Give it plain water and wait 3 days,,,,if the drying continues into the buds....harvest NOW.

Next grow run Dyna - Gro "grow" all the way from start of feeding to the wash.

Your about done. I wouldn't worry about feeding it anything just water.

There is an amount of Yellowing/color change which is perfectly normal 8 weeks plus into flower. I think it has something to do with Buds sucks sugar leaves dry useing nutrients and energy for flower growth. The question is in the plant healthy overall, how extent is yellowing, just older sugar leaves or is it in the trim/bud leaves that are yellowing.
Alot of my strains will finish at week 10 or 11 with barely any leaves just buds. most of the sugar leaves, or "fan leaves", the ones with no major trichome growth will yellow and fall off naturally. get a pic up and can tell real quick if natural or a problem.

this my last harvest for reference had plenty of yellowing near end but does not hurt quality let it go till you got you 10% amber
