Hungry little girls....they look starving besides the plant in the back left.

Something not right with the root zone. Your system is a little confusing. Are you watering 24/7? An i reading that correct?

You think so? The mix is 820ppm right now. I always go a lower with the nutes then what the bottles call for

As long as your PH is correct....the plant looks like it has Nitrogen, calcium and possibly phosphorus deficiency starting...

He is in coco....he has to water often.

looks like phosphorous deficit maybe too much of something is locking it out .

Yes the autopot is all bottom fed so they are setting in water 24/7 with this system. I have had this issue before an finished the plants out. they looked like shit and have still grown nice buds. When i am done i always check the roots and they are all nice and healthy looking. Here is a pic of what my roots look like on every grow when finished.

are you following the AN schedule exactly as they list, deviation usually causes trouble

No i am not i found the mix seem to be to strong. or maybe i was looking at the wrong schedule

The best thing to do with AN is throw it out and get a different brand of nutrients....

Yeah those like fine. My problems tend to come around when I let things sit in water so thought maybe you rotted the roots. Your either locking nutes out or under feeding. Just gotta solve which one.

I think the problem with AN is you have to buy the entire line up for it to work. And who the fuck wants to dick around with 10 bottles.

Hell....I bitch using 4 with cal-mag as one of them lol

honestly i have the same GMB in my drawer aswell. it says to start 2ml/l GMB then eventually 4ml/l i found aswell it burned the ever living shit out of it. but for some reason reducing the amounts shifted the total PPM need. see really the 3 bottles together are supposed to proved equal PPM over the 16 macro and micros, but they always have to be in balance or you will start antagonizing some elements because the balance is out of whack. where they want you to be hands off i found i had to work harder. try feeding the recommended amount it will have proper PPM balance throughout i hope this makes sense

ive.since changed to megacrop but might also give Jack's321 a chance

Thanks guys I am going to up my mix to 4ml per lt and see if this will help.

Bullshit. It’s a poor carpenter who blames his tools.

Most people don't realize they can feed their plants with things legit laying around your house.

So I did a 18lt mix with what the feeding chart shows and i am getting 1143ppm lol
