no, 'alternating' means the stems are growing off the main stem at alternating points, instead of opposite each other (hope that wasn't too vague) ... you can flower at any time you want, BUT, you will lose much potency, growth, and yield ... I always veg for a minimum of two months ... I go to flower after my plants are a couple feet tall ... that way, you have mature viable plants that are capable of good yield and potency ... growing is an exercise in patience, but, it pays off BIG ... same with drying and curing, don't take shortcuts ... good luck there ... :smokin:
