Does anyone have experience using RG Tupur?

I’ve just started a few auto seedlings in Royal Gold tupur mix. I’ve been treating it like coco and have recently had brown spotting on the first set of leaves. Unsure what the issue is whether it’s pH fluctuation or calmag def.

Wondering if anyone here has used it before and if it should be watered just like coco as it’s not 100% coco/perlite. It’s listed as coco, aged forest material, basalt and perlite.
Any advice on how to water/feed seedlings in it would help. I know their site says to water/feed 1-6 times daily.

Here’s a picture of the issue I’m having..
