How common is nutrient shock after repotting into All-Mix?

I don't know but if that happened simply by potting up and a few days, i'd never boy that medium ever again, lol. But, this was potted up at least 15 days ago according to diary? I think this is something that has happened in the meantime and nothing to do with potting up..If you haven't fed since then, i'd wager that's the issue. Since it took a long time to display symptoms, i'd also lean toward deficiency rather than toxicty or 'nutrient shock' Also, any defoliation for the sake of defoliation made it less robust to what has ensued since, too. Leaves are like hit points in a video game in that respect. You'd still see issues, but there'd be more room for error fixing it. ensure your pH is fine.. get it on a regular, conservative and balanced fertilizng program to start... The symptoms sure aren't orthodox. starting at lower and mid level leaves (at least partially mobile)... crunchy on ends, first, then spreading and curling... it should be coinciding with some other symptoms to match up to either low k or low mg, but those aren't seen. Mb? if so would more likely be pH than an actual matter of low trace elements. maybe the coco wasn't properly buffered, but if you've used the all-mix elsewhere, you know about this already.
