Flowering time

yeah, probably damaged the terminal bud or the stem leading to it.

Something like bud shaving / budding happened, aka you damaged/ influenced ( late top for example ) top cola some time ago and it went that way. Or its some early prevented foxtailing. For sure not common mutation, more like aftermath of damage....

Hi bro, Regarding watering for plastic pots, how often are you watering them? Plastic pots tend to dry out more slowly. Brown leaf tips can indicate nutrient toxicity. The frequency of watering depends on how long is left until harvest. If you have time, flush the soil with pH-balanced clear water in preparation for future use. Check the pH level of the runoff water and try to maintain a consistent pH level. Avoid overwatering the plants. Best of luck, buddy!
