2 week old seedling, rdwc, ec 1.0, ph 5.9.
Spots are on ends of leaves. What do you think?

It looks like calcium deficiency. I reckon either give more calnit, or calmag, or increase pH a little bit.

Perhaps someone else will chime in.

EC 1.0 at this stage? I think you should look there first.

I think you should just use soil. I don’t understand why people want to complicate such a simple thing. Unless you’re like a production grower with production type goals soil is king( even then soil is better but speaking of the common scenario)You will have far fewer issues.
