I planted in containers that were too small, so I went back to vegging
after a few weeks of flowering. Plants responded well! I repotted to
allow for more root growth, as this seemed to be the limiting factor, and
plants grew nicely.
Returning to vegging may help rid overabundance of ferts (esp. nitrogen);
a little extra time under 18/6 can do nothing but good. An extra 6 weeks
vegging can turn a setback into a winning situation. Good luck!
