Weez,

You are THE MAN. Moving the light up fixed it all. The widow was a little shy on Mg, but I gave them all a feeding of half strength nutes, and sprayed the WW with some epsom salt water. All good.

Thanks so much for the input. Soil is still a little high in PH, so I'm feeding at 6.6 rather than 6.8 until I bump them up to three gallon pots. I will be sure to check the soil PH before I transplant!
