    My fan leaves keep turning yellow and then dying and getting crispy. Lots of pics.

    What do you guys think?
    My water has alot of salt/TDS in it. I run it through a brita filter but that does nothing for salt.

    Also could be rootbound? Tried giving it just water tried giving it low dose nutes but it doesnt seem to get better.
    Its in FFOF soil with Jacks classic nutes.

    Also the tips were nute burned previously, then it was healthy, now this :/.

    Sodium build up? If you can remove the dying leaves, would probably help. Beefy Buds though, good shit =)

    I think u have locked in Mg ... Do u correct ph level of water then water the plant?
    If some nuts locked ,It cause others nuts locked ....Yellowing it about low N and Mag def I dont c Cal def ...
    But if u not cure and help your lady ASAP shes gonna wrong ...
    I advice use CAL/MAG and correct your ph ....
    Do u use ppm meter ?
    Best wishes

    what kind of nutes? something high in n?

    You look like your almost done, don't do anything. Just continue fattening them babies up. No nitro at this point, just keep doin what ya doin.

    If you use twice the amount of water and same % of nutes, It'd be even better.

    Well i thought my FFOF/Jacks classic nutes would have enough N in them. I was using 20/20/20 until the second week in flowering and then i started giving them low doses of 1/3/2.

    No PPM or PH meter i probably should get them for xmas lol.
    I doubt its Cal Mag. My water is pretty high in both of those and i even added epsom salt at one point because it looked like Mag def. If im not getting enough mag its because the salt, PH, or something is locking it out.

    Yah i gave it a good flush earlier so hopefully that slows the decay :/

    you need to give more nitrogen in flower, that what it looks like to me.

    Did that start on the bottom fan leaves and work its way up??

    BlazedMonkey Well-Known Member

    More Nitrogen? Do you think its because i wasnt feeding them enough or was it lockout from something?

    Yah it would start at the lower/middle.

    Many of my plants do this toward the end of flowering. I never figured it out. I tried flushing some, neglecting some, not changing anything, giving them lots of nutes, etc. Nothing ever makes a difference, they just start looking sick and dropping yellow/brown leaves. The buds never get sick though. And the dried product is always super kick ass, and that's really what I care about, so I left it at that.

    I have a cole train that is at 10 weeks that is doing that. It's looking sickly. Smells like gods vagina though.

    Interesting, yah the buds look nice. Next time I'll let it go further and see what happens.

    Thanks for sharing though :)

    I agree with this statement... mine are doing the same... as long as it is in last week or so of harvest you are fine... from everything ive seen, and experience has proven this is the case. It is supposedly bad to add too much nitrogen in flowering.
