I have leaves showing up on a plant or two that are variegated on half of a single leaf, dark healthy green on the other half. This is only showing up on some leaves of a plant, not all of them. And, some of the leaf tips curl radially, as opposed to up or down at the tips. I am using hydroponics and am wondering if I am missing some micro nutes, ie molybdenum? Any hydro experts out there ever see a problem like this???? The variegated parts almost look like some bad type of camo gear. Not yellow but light green with other parts of the same leaf perfectly green. Whazzup? The plants are doing great otherwise.
