Flush has been done I ran 20 gallons over her I kept testing the ppm run off while I flushing and after 15 gallons it was still higher then 250 ppm so I added 5 more gallons and got it around 150 ppm. I don't think you can get it to zero unless you really flood it out for a hour. Bud are fattening up they love the water only.
I couldn't upload the recent video don't know why. but i could post it on my weedtube https://www.theweedtube.com/video/trainwreck-autoflower-44536?commentId=c86f2c94-6faa-4b54-af61-e2f114e3f33a
Hi @Fitzwell! Magnesium, manganese, potassium...at this stage, there are so many symptoms that it's hard to tell. These make me think of a nutrient lockout, the root mass could suffer from old nutrients/salts left in the medium. Do you measure the EC/ppm of your solution? Do you feed everytime you water, or do you give plain pH'd water sometimes? I would recommend to consider a 2 weeks flush before the chop. Happy growing! 👊
