Plants continuing well. Not too big after first week, but in a large pot, that is to be expected. The growth explosion will come later.
15/6 update: Very fast progress. Two nodes in, working on third. Both roughly in the same stage, though the one that stretched more is a little smaller. Will be interesting (and maybe painful) to see how the effects of early stretching (and my lack of diligence) trickle down to later stages of growth.
Also, some leaves are a bit shriveled - idiot me has realized I've not been adjusting my PH for coco, so likely from too high PH. I've adjusted it down, they will be fine I'm sure.
