Man, I gotta get this figured out as it doesn't appear to be getting better on it's own :jointsmile:

I'm certain it's not too much heat. I'm pretty sure it's not lack of air flow too as adjacent larger plants are showing no sign of this. There's a possibility that it's too much water, but based on how these symptoms presented themselves I don't think that it is... It appears to be getting worse still as it dries out. I tend to water on the light side I guess.

Could this be related to a Cal/Mag problem? I'm also seeing the rust/brown spots that are signs of Cal/Mag problems. I think my pH dipped pretty low (runoff at 5.3 - 5.5) for awhile...

This is happening to 2 plants. I guess I'm going to flush 1 and see what happens even though the soil is still pretty moist.
lampost Reviewed by lampost on . I thought this was canoeing leaves Ok there's another post right here about canoeing leaves, but I didn't want to jack someone's thread. Besides, these leaves look different. Anyway, here is a picture. There's only one plant that is doing this out of a few.. I think a second one may've shown signs of it. It's not on all of the leaves but on several. Anyway, what in general are the causes of this? I thought my temps were ok, but I think it may be heat or light because it happened to the plant directly under the lamp Rating: 5
