I think I nailed it though. I gave them a buffered pH 6.4 water around 4 hours ago along with a pure water misting. They're all in full prayer again, the last 2 days they've looked a little less happy so I've been keeping an eye. Just after I fed a tea. So that was at least part of it, the slight yellowing bit on a few leaves at least was pH related. But mostly I think the black spots were thanks to the canola oil being over done a bit. Reason being that they are also on a little plant I am re vegging that had none of the low pH tea. Didn't cook this mix long enough I think, undershot the lime a touch too. So we learn. Would still love to see your pics, will get some up tomorrow of the worst looking leaf, its in a spot where I was going to trim it within the next week or so anyway to open canopy a tad. And I forgot to add that indeed they are flowering plants...
