buddy has been flowering for 4 or 5 weeks...two different strains that are indica-types with around 9 week flowering times for both..

so...they have been flowering 5 weeks or 9 weeks?...or did you start 12/12 from the beginning?...anyways...I would just flush with Ph 6.8 water and wait and watch the new growth. If it's 5 weeks...a transplant MAY help?
