Hi Aaron,
Hey, thanks for sharing the link to that thread. The responses so far look a bit speculative though. For example, if its Fe then one ought to be able to reproduce the effects by withholding and then dosing large quantities of Fe with repeatable results. I'm sure it's a combination of light and nutrients but haven't figured out which combination. I'll keep checking the thread to see what good ideas comes up.

Cheers,
