Could it be that there are two different strains? Actually both are Lemon Wonder. The leaves are different. One plant is more thin and elongated, the other plant is thicker and shorter. Is that normal or are they really two different varieties?
This is what you call Phenotypes. Think of it as two brothers. Both same parents, just difference looks and traits. I have two polar express plants going right now. They are conpleatly different than each other. One is showing dominant Sativa and the other is defiantly a more hybrid.
