"Life, Uh, Finds a Way".. No need to re-top she just has some vigor and really wanted that part to grow ha ha. Because the growth is substantially slower on the new/fresh node no need to re top as the Side nodes will become the dominant growing parts of the plant. Watch and see .. As the rates of photosynthesis increase from the larger grower parts she will grow out towards the two tops. For my canopy control I just clip large canopy covering leaves and the plats tend to grow themselves because the parts with more leaves will grow faster.
