Canna terra professional pro+

Wondering if anyone has any info that suggests this soil is too hot for autos? I switched recently from happy frog, and now I have what appears to be nutrient burn on my 2 week old critical Jack. Haven't fed any nutes yet, just plain ph'ed water.. I'll take a pic and post... Any Input is appreciated!

Here's a few pictures. The last one I used a flash...

What's happening?

That's what I'm trying to determine.. R u using the same soil as me?

I've never used that soil but its safe to say that soil is a bit hot .... its not too terribly bad im sure they will power through ....... the description i read for the soil said " charged with fertilizer " its sounds pretty loaded , I'd bet you could mix that stuff half and half with peat and it would probably be a good mix
