Dark/brown spots on leaves

[CannaGrowerr]

Hey everyone, one of the plants has dark/brown spots on 2 of the lower leaves. Adding pictures below.
Growing in soil. (canna terra pro plus)
The plant is about 16 days old.
Need advice what it could be? Could it already be a deficiency? Or is it some kind of pests?

It's 2 leaves. I'll post one later on when I get back. Actually I've got a picture of the 2nd plant which has similar spots. I will add it below now. I might have transplanted them a few days too late. Could that have an effect? What do you think the spots could be?

Soil looks really dry as well

Looks hungry, that soil doesn't have much food in it, designed so you can start feeding earlier, it will probably will take a few days for the roots to get the new soil if you have recently transplanted

Do you know if you have hard or soft water? It may need some cal/mag. Just a thought.Sure someone else will chime in on that.

Thanks for the reply. Wow I'm confused now. Someone else told me that it might be nute burn causing them spots and you're saying the opposite hmm. I mean your theory probably makes more sense. Because I haven't fed them yet. Been told that Canna Terra Pro Plus has elots of nutes for at least the first 2 weeks so not sure.

Just to rule it out, you don't think them brown spots could be some pests or spider mites? It's probably some kind of a deficiency? Thanks

The tap water I've got apparently has almost non cal mag so I will add that on the first feed in a few days. Main thing is I wanted to rule out pests/mites. If its just some kind of deficiency then it will be easy to fix. Thanks

Don't look pests to me , but I don't really know never had any kind of pests though, I'd say slpash marks then the lights burnt it
