Leafs curling down

You did the right thing to flush because they are over fertilized. But you wont get an over night fix.

What ppm are you feeding?
 
Highest I went was 1010ppm.
After I noticed them curling down I went down to 600 ppm, still didn't go away so I did a flush and regular water feed, and I did a revive feed by advanced nutrients. My run off water is at 420 ppm 5.8ph
It's been over a week now

Most of the time the curl wont be corrected even after a flush. Keep watering them at 600-800 ppm. I would aslo cut any additives out and just use a base fertilizer.

I don't and won't use anything from AN so I can't help there. But I will say that "revive" is most likely a waste of time and money imho.

They are, the "cur"l is a sign of over fertilization. You caught it before they got too bad. So kudos to you.

The good news for you is they aren't to the brink of death. Just keep on feeding with base ferts and you should be good.

What fertilizer are you using?

What fertilizer are you using?
Canna coco A+B week 1-4

Boom! thats the problem right there. Thats why I kept saying just use base ferts only. Don't worry about additives till you got your process down first.

Moab has way too much pk and is not needed. It creates lock out and burn(or curl/the start of over fertilization) when you use pk boosters too early. If you are gonna use it wait till week 6-7 and use 1/4 strength only.

I thought I was nitrogen toxicity so I emitted the base nutrient and added only MOAB. I see the problem now. Thanks
