Any updates or new info on cause or cure? I came to these forums today specifically to do a search and try to figure this same problem out. Some of our plants have been doing this for the last couple years. Most will do it at mid growth and then turn back to green before maturuty and seem okay. Some aren't doing it until late in the season just before harvest. I've had young plants that turned like this die, but the larger plants seem to get through it. I'm just lost as to how to treat it but next year I'll take the advice I read here about raising the PH and giving them some "sweet feed" to help get them through it. I'd sure like to hear any new information about what causes it and how to prevent it though or even a heads-ups to other threads here that discuss it.
