I honestly don't know anything about AN nutes. I just use GH and the lucas formula. Did it get too cold? Something killed that thing. Maybe it just grew old and died, I dunno. But, looks like something killed it. Does your wife or a roomy hate you and maybe it gotta shot of weed away grass killer?
I figure eventually someone will chime in. I see you are doing DWC and I've only done that once. It's such a pain in the ass keeping PH's right and although I was successful, I just don't like that style of growing. I have heard, that DWC can kill your plant fast. I do Hempy and feel it is more forgiving just using common sense. Anyway, best of luck bro, really need a hydro expert to help with this situation.
Dude you feed the plants what they need. You can even feed them a little more to see if they can handle it. But, you can't force it down their throat. The medium hydro or whatever is their environment. You made it toxic. Best of luck.
Well better luck next time. Get a good meter and simplify your nutrient regimen. You would be miles ahead to just use a 2 part GH with a bloomer at this point and then ease into additives at 1/2 strength as you get your grow touch down. I have a friend that started growing hydro and when I asked him about his ppm nutrient level he says I don't need that, I just follow the instructions. He made it through 3 grows and then well pretty much same thing. It's like skydiving without an altimeter, you just don't do it.
