Purple cousins

Seems like they’re shooting up pretty fast but the Coco dries out fast! I need to keep it hydrated probably should’ve started with smaller pots as there is a lot of soil per plan at this point. trying not to oversaturate as they will fall over and have to prop them up, doesn’t seem to stress them out but don’t want to keep that happening trying to gently put the fan on him to get a little sway. What to build up that stock so we can support itself.
