with bag seed you dont know for sure the strands your using, so no uniform look will be present. Personally I dont reveg, but it is possible if you clip the bud tips at the end of the stem and leave the rest, it will reveg, just looked deformed and take a long time. May be better off with a store bought more secure strain to start off with again, and clone those. Bag seed isnt usually very potent, there is exceptions, but you may be better off, growing out ten store bought seeds, pick the best one and clip it for future plants.
