Yesterday I was thinking magnesium when it looked like this. Now I'm not so sure, because this is how it looks today.

Any help would be much appreciated. Thanks.

Didn't get extremely hot. Mid eighties which isn't great but never been a problem before. I know it's a deficiency because I have one other plant of this strain and is showing the same symptoms. What does the attached picture look like to you?

I know you see dots on the pic but if you look at the leaf underneath the one you took a picture, that looks like water or heat stress bc of the canoeing

I have a small fan providing air circulation. I really don't think it's heat stress and I've kept the soil evenly moist.

Like 20% runoff and all that?

Assuming only one plant would show heat stress is a mistake.

mag and P def, from lockout?
that is my guess.
make sure you have enough drainage. as your already in flower its probably to late to fix it.

No I gotta be honest that doesn't look like any deficiency it is definitely stress, if it's heat stress it's weird that a lower leaf would experience it first, unless your using cfls, what are you using for lights, if your using hps and it's within 2 feet of the plants it's definitely not heat stress, you would see it on the top leaves first. If it's not heat stress I would guess water stress. Do you have sufficient drainage?
