Did you mix anything with your oceans forest? And did the spotting start before or after you transplanted? How about the coloring in the stems?

I wonder about bugs of some kind.

YIPES....they are white widow babies!! I myself would consider FFOF too strong for WW' babies and keep them in Happy Frog. I also agree with sensi lights that your pot may be too big for them......something about 1/2 to 2/3 that size but FFOR is a hot soil and WW likes VERY LIGHT nutes.
