I thought this was canoeing leaves

Looks like pH problems that happened to me, I never got it fixed for that plant so sorry I can't offer any advice.

That sucks.

I got the pH up a little bit. I think this might be related to over-nute though or a combination. Either that or this strain is extremely sensitive. Other strains had runoff at pH 5.0 and they are doing really well.

Good luck getting it dialed in, it's really heartbreaking when you put all that time and effort into it and end up with something like the plant on the left in this pic. Same strain as the other and everything else almost identical but different soil (lost its buffer).

I don't mean to rub it in but that one on the left is so pitiful it's funny.

I feel your pain though.

Damn, there's no way to bring it up once it starts losing it's buffer? Or was it just too late for that one?

Didn't really think too much of it until it had maybe 3 weeks left...

This is what it started out like in early flower, on the right this time and the other on the left

This pic is what it started out like in early flower, on the right (3-4yrs stale no name organic soil) this time and the other (fresh FF soil) on the left. About a week after that pic, the leaves started getting a rust looking layer forming in the middle & starting with the oldest fan leaves. I flushed like you did and it seemed to stop the progression for a few days, then it came back even harder with other nutrient deficiencies and nute-burn looking symptoms. I looked a little for solutions this late in flower but ended up just continuing as if everything were normal. I tried smoking a bowl from that plant and it was very funky tasting and generally not so strong so it's in with my growing pile of trim that I'm saving for some hash. I think there was about 3-4 grams of basically sticks with a few pairs of preflowers runing down them. Even though it was a dwarf autoflower that's still extremely pitiful: I almost didn't even save it.
