I have kind of bounced around. At first light related? Raised HLG 260 from 25 to 28".
Nitrogen - no rest of tips would show something
Magnesium - would expect to be
lower leaves and not at this height.

I do not see any other leaves that at affected. Or on two other plants
What say you

I say don’t sweat it. Probably something happened to those leaves. As long as it doesn’t spread to other leaves, your plant will do alright.

Nice looking plant…

Thanks. Hopefully it is just one of those things.
It / They were just topped the 2nd time today for a manifold. I want them to be a little more vertical before spreading them out.

It looks a lot like the nute problem I developed when my autos went into flower. My photo developed it too when I transplanted it.

I brought my pH down into the proper range, increased my feeding to 110% Jacks, & run Cal-Mag only for one feeding a week. That seems to have mostly fixed it.

This is what mine looked like for comparison:

I forgot to mention, I also flushed with pH adjust water just in case I had nute lockout.

But I had been using water close to pH = 7 prior to my problem developing.

Other than the two spots, they look wonderful! It looks like it might be the first set of true leaves, maybe when they were young they touched the soil some and it’s just not showing up? :+1:t2::v::sunglasses:

I’ve got a couple in coco/Jack’s doing the same thing: I’m sure I splashed nutes on them.

hope it is something simple like that. I try to wipe the leaf off if I do get them wet. Thanks for the peace of mind
