Once seed cracked i planted seed on this soil. Is it too strong for the seedling? Am i already in trouble? xP

So far doesnt seem like it was too strong for him^^ Thank you all for your opinions on the subject! I'll be choosing the answer once the seedling tells me who won xP

Yes, rather strong for seedlings, with too much guano, for my preferences. Mix it 50/50 or even one third/two thirds with "seed raising mix" and that would be kinder for your seedlings. Baby seedlings need baby feeding and 14/16/18 is too "hot" for baby plants, look for something softer and with single digit N/P/K values.

Im going to guess the soil is definitely to "hot". Seedlings do not require much of anything for a week or two if growing in soil.
