Do Si Dos [BAG SEED] + Mimosa [CLONE]

F1 got topped today and I did a bit of LST and tucking to her as I thought she looked about ready. F2 looks as if it has topped/fimmed itself or it's growing very strangely cause it has a bunch of tops in the middle instead of one. F3 looks funny I'm not gonna lie, she has the weirdest growth I've ever seen, maybe due to it almost dying during germination or maybe it's just not a very productive bag seed in general. Not sure whether to keep F2 + F3 or keep F2 only and try experimenting the mainline technique on her and get her transplanted. Possibly I'm gonna ditch them both in the end anyway, who knows. Mimosa started thriving well so I cut the bottom leaf off as it was annoying me when watering and just generally looking at. Think I will leave her a bit longer before deciding whether to top her or not and train her down.
