please give me your advice and tell me wat the f*cks happening

if more photos are needed just ask, please refer to which image your refering too if applicable guys

You should give us a more detailed accounting of temps, humidity, what nutrients + additives you are giving her. How many weeks of flower so we know if the plant is on track. I wouldn't stop there though I would explain my type of lighting, soil type, planter size, and everything I could think of.

Bland answer for a bland question:
It does seem like you may be exceeding that plants maximum temps so yes I would back off slightly. Also it seems like you are possibly putting many different things into the nutrients solutions when watering. It may be as simple as not setting your pH. It could be as complicated as putting raw coffee grounds or excess molasses. It also appears you are a little rich on Nitrogen but I see no root related damaged from excess N.

so this is just a simple issues with feeds, its on a wilma system, using dutch pro a n b base feeds.
They were badly stunted week 2 off flower and dried for 5 days, i axed off many badly hurt ones and kept these few, their timing is now a mystery, im going to give the whole lot two weeks more.

but this is not a problem that will spead plant to plant, at the moment also they are on potash and overdrive too.

soil mixed with clay pebble and perlite is the media,

these plants went through a real bad time and displayed many problems over the course of this time. im not supprised to see problems on one at least still

The plant has too much n, as for your second question it looks as though you already are.

N tox is usually caused by the grower, either by feeding to high nitrigen feed, ir by locking out other nutruents through the ph levels of the watering solution, possibly both, what are you feeding her , what is she growing in, and what is the ph of your water/ ferts?
