Nutrent toxicity??

Been growing in Fox Farms ocean forest soil using the trio nutrients have had no issues of nutrient burn or any issues up until flowering I stop using all nutrients about 4 weeks ago two weeks ago I flushed them and I'm still having these issues not sure exactly what it is or how to treat it

I don't use soil or ff but usually speaking if you have a build up of salts in your medium you would not necessarily notice it until half way through flower.

Some nutrients get locked out due to the sheer salinity of the medium, the ph is usually out of whack too for the same reason.

1st pic looks like that, 3rd pic shows massive salt build up on your fabric pots.

So what should I do flush it I was reading something about using vinegar

No don't use vinegar.

Flush them with a really low EC nutrient solution. Put a gallon of water through one first, collect run off and measure the ec/ppm if you have a pen/truncheon to do so.
You will probably find it reads like 3+ EC.

I flushed the shit out of em then I gave em a light watering with nutes and so far so good the ph dropped back down to 6.8 I'm just hoping they snap back and finish up flowering so I can clean the room and start my next grow

And the run off was like 9 ph and 900 ppm when I was flushing
