The sulfur deficient plant is iced grapefruit. The one with the deformed leaves is Trainwreck.

Bump. Any ideas? No bugs under leaves, same soil water nutes etc vs whats being used on about 10 other plants at same age.

The one you suspect is sulfur deficient, yellowing top leaves, looks to me like lacking iron, usually caused by too high PH.
But I'm not familiar with what sulfur problems look like, you could be right.

What PH are you watering with? I predict over 7.
Or if you are keeping that in check, could your soil have really high PH?
