That's a sulfer deficiency?!

I dont know if it can be foliar fed, but I do know ammonium sulfate is cheap... you can sometimes even get it at walmart in a 20 lb bag. It's used as a lawn fertilizer. There might be other ways to add sulfer but plants and soil tolerate ammonium sulfate well so I dont think there will be any downside to using it. Sprinkle about a half cup around the plant. Lightly water the soil surface in the morning... It will begin to dissolve. It should all dissolve within a few days.

Plant marvel is advertised as complete nutrition but it appears that it lacks any sulfer unless you buy the high sulfer version.

I hope I'm right, I'll will certainly feel like a fool otherwise.

oh wow! I just watched that video and those leaves look very very similar to what all my plants are doing. I will see if I can find some of that stuff. I guess it is worth a shot
