I'm having the same problem bro and you say you've flushed eh? I'm inclined to think that it could be a lack of P since you flushed for so long. Hopefully we can both figure this shit out.

I feel your pain. I have the same issue. I'm supposed to be at harvest time (10 wk flowering this wk/strain guide says 8-9 wks) All my leaves are yellow and dying. I've flushed for about 2 weeks now thinking they should be ready by now. I still haven't seen amber trichomes but seeing some cloudyness. I've heard yellowing is supposed to happen but I'm just about out of leaves except where they nestled in close by buds.

Should you not still be using AN Overdrive at this point? Overdrive NPK 1-3-4, with your existing chemicals? They may be missing vital ingredients in their diet at this crucial point in their final development. It doesn't look very alarming as your buds seem to be doing well. I'd make sure none of those dying leaves do not make the bud go funny (botyrus eg)

it looks to me like you're using a super phosphate (something with a ...- (40-60) -......

these ferts are NO GOOD for pot, they're made for fruiting plants and roses. using a super p regularly will cause a p overload, which will alter ph and end up locking p and k out. (ask how i know...) leaves end up crispy and dead, though the plants are still growing.

i could be wrong, but if i'm not, keep flushing, and use light regular nutes with a level npk.

If you're 2 weeks from harvest you should be winding down on nute supplements anyway... so I wouldn't worry about it. If I were you I'd flush and flush and straight water for the rest of the grow. Your plants are looking fine other than the recent problem!

I may be wrong, but your plant may be fininshing up and the needed nutes are being pulled out of the fan leaves. Do the buds look good? if the buds are fine it may jus be nature.

same thing happened to me, I think it's just a natural part of the plants life, it happens to most especially that close to harvest. I'd flush with water, and let the plants finish up.
those buds look amazing by the way.

I agree, totally normal. Stop the nutes now, and just water with plain ph'd water till the end. They look really nice. Maybe another week to go with plain water. :mrgreen::peace:
