Reveg?

yes you can re veg, i have done it in the past and worked out great. you harvest almost all the buds but leave a branch on with some growth, put back in veg and give veg nutrients, change light cycle. re veg. it seemed to take about the same time as when you flip to flower you know that pause, like a week or two. then you see new growth, let it grow some and after you have enough healthy leaves pick off the older growth from the first flower, . hope this helps, it does work and is easy to get the grow going again
