I want every grow to be the same :0/

Is it true that some strains can suffer with TOO much nutes in their starting soil for seedlings? I have been using Happy Frog as the soil from start to Finnish.

All strains can get burnt and seedlings are extra susceptible. If your starting soil is strait from the bag you are probably good. Assuming it in new, strait soils appropriate for cannabis. You don't want to just add a bunch of amendments to a seedling. After it is two or three weeks old you can top dress, up pot into a richer mix or start adding liquid nutrient.

If you are using soil straight from the bag for seedlings it's usually recommended to flush it out first before use so there's no nutes available straight away.
I usually recommend using seedling and cutting soil and certainly if one is growing automatics, a lot of people do be burning away roots on seedlings resulting in slow growth and expansion.

Now I did try cracking the seeds in amended water last time, with Great White Myco & Rhizotonic which does contain 0,6/0,2/0,6 NPK and used that to pre water the soil for the seedling and these plants took off like crazy

Here's one of them at 15 days.

Its gotta be, from now on im only doing seedling in soil, i’ll save the castings and nutes for a plant that has a nice root structure

Castings are mild enough that you could start seeds directly in them, but they can be too dense so fluffing them up a bit with perlite or something can help. So, castings aren't your problem, but nutes are generally too much for a seedling.

My seedling mix is equal parts castings, well aged compost, old soil and perlite. The castings bring microbes that start breaking down the other stuff so it starts to become available to the plant once it has mined what it can from the seed leaves.

The castings also help fight off damping off disease which can plague new sprouts, especially with a wet soil surface.

If you're getting consistently poor results you need to dial in your variables a bit better. Not every grow will be perfect, but you'll learn a bit every round that can be applied to future ones.

Keeping a journal on here and asking for advice along the way is a great way to accelerate your learning curve .
