Growth update for today. Having concerns.... Discoloration like this appears in a couple spots on plant B. A deficiency of some kind? (Nice shot of the duo) These are 3-gallon pots.. Should I be concerned with root-bounding?? Even when I transplanted, the roots were dense and circling the bottom of the smaller containers.. Do the roots expand while flowering also?? If so, I may start 12/12 sooner than I planned.. any input?
