for an auto ,, that is one nice plant, most that ive seen and grown dont make it close to this stage before they are deficient in some micro nutrient only found in minute quantities on the third moon of europa, and need the exact color of light available only on the blue moon at noon in the third week of august for six seconds and have to be watered daily with triple filtered reverse osmosis desalinization run off from the summit of an erupting volcano somewhere in the southern pacific., but i digress, foxtailing (if thats whats happening) isnt always a bad thing, and while we r on the topic, why did you cut all nitrogen,, if you actually did , that might be part of the problem, i use nitrogen amost until i flush right before harvest,, buds are green also and sugar leaves NEED nitrogen,
