Help one dead (very quickly) three left

Hi, this is my first grow... everythings been smooth, some difficulty during flowering though... ok
I use distilled water
outdoor grow
they get 10 hours of sun a day
feed with water soluble 9-14-8 african violet shultz bloom booster and colorburst 15 30 15 granules.
i know it isnt nute burn, if anything i feed them less than they should cause of burn fear
theyre all about 7 feet tall probably sativa theyre really bamboo like, used bagseeds

so 4 days ago my thickest one started to wilt and get muddy brown rubber leaves... 2 days passed with no action because i didnt have my test pills and it shriveled up like a raisin and died... every leaf at once.EVERYTIME I HAVE TESTED THEM THEY TEST WITH LOW OR NO PHOSPHORUS AND ADEQUATE IN NITROGEN AND POTASH... i thought it was from the ph being to high... it had been at 7.0 for almost the whole grow, so i brought it down with natural remedies and now its sittin pretty at 6.0 which i thought was supposed to get rid of phosphorus lockout but they still arent getting any... the "death" as i call it, starts from top to bottom, most fan leaves fall off really easily i dont pluck unless they brush off in a breeze easily... but now the vegetation around the top flowers is wilting and getting that same muddy brown and the tips of a few pistils are browning... i know its phosphorus I JUST CANT FIGURE IT OUT I LOAD THEM WITH PHOSPHATE RICH FOODS ORGANIC AND NOT... THE PH AS FLUCTUATED WITH NO CHANGE... SOMEONE PLEASE HELP I HAVE NO PICS CAUSE NO CAMERA............ (you wont find another hobby with such active forums full of helpful nice people for a better cause than growing marijuana.) GROWIN DOPE IS HARDER THAN IT LOOKS

add pot ash
or get some tomato feed, its prety cheap

Can you please explain why? I said potash tested more than adequate.

I also have red veins on the one that has the worst symptoms of P deficiency. Since I first posted that "one" has dried and browned on the tops on the tips around the flowers... another symptom is the tips of the leaves shrivel and roll up muddy clay then brown... they sound shitty but they still look good and fruitful, the best advice I ever got for this hobby is to diagnose symptoms quickly and fix them, but I am baffled, and worried about my girls.

PS: I live in the south and it has been pretty hot for them (95degree average), I planted a little early... early april, they are three weeks into flower, I've been forcing flower... scheduling it so theyre up for when the sun isnt so hot, spritz them with pure water ingredients H2O every 2 hours when they are up..

Thats a high Phos your feeding, maybe your gave it too much and now its phos pipes are all clogged up

maybe this is wot ur doin wrong mate. no misting with the sun is up lol
P.S. even when the sun "isnt so hot", if it touch misted leaf, the leaf will die very quick.

hmmm.... my outdoor plants are in same conditions too.

it must of be something with the nutes...

pretty windy not rough though i have a tarp cutting some of the wind off... if the P was getting clogged up it would at least have some P in the soil, the ph lockout sounds right but im not sure which level to put it at, ive checked a lot of forums everyones problems seem different than mine
