Organomananswered grow question 3y ago

Yes, there is some burning from too much nitrogen, but the yellowing is an indication she is hungry for phosphorous and potassium now that she is flowering. Cut back on the nitrogen and give her a dose or three of a P/K booster and this will help her continue. The damaged leaves will not recover, but it will help keep her other leaves healthier. Hope this helps, Organoman.
