Organic soil is kinda like cooking - there's more than way to skin a cat... have a look if your stuff has any NPK info to understand what each ingredient is gonna bring to the mix.... Not too familiar with auto's but in general you want to start your seedlings in a 'plain mix' (e.g.

Base:
1/3 peatmoss
1/3 perlite
1/3 compost (not sure how 'hot' your manure compost) maybe mix your manure compost with EWC (earthworm castings) at a ratio of 1:1
Amendments: (per cubic foot)
1/2cup Bat guano (most often this will be high in P) 1
1/2cup Seabird guano (high N) - not sure what you have hear - if its a guano enriched compost or if its just straight guano
1/2 cup bloodmeal (I'm not sure but this one may be considered 'hot' and you'd need to mix this into your soil and let it 'cook' for a few weeks - basically it has to be broken down a bit before planted in) - hopefully some experts can confirm or correct me on this one
