Which is better organic Soil Mix- Advice Please-Autoflower Balcony Grow

Hey everyone. I thought I`d repost my thread in the organics section (hope thats cool with moderators) to try and get some more info on my question from a different perspective. Looking for some advice from experienced outdoor growers to help me choose the best pre-made organic soil mixture. I don`t have access to the top-notch mixtures I`ve been reading about (e.g. Fox Farms, Plagron, etc.), so I`m going with the stuff from the garden store.

Here`s a brief grow environment overview so you can steer me in the right direction

Location: outdoor, south facing apartment balcony (6-8 hrs direct sun), northern hemisphere/european alps
Strains: Autofem Pineapple Express (Barneys Farm), Autofem Snowstorm #2 (Dutch Passion), Big Bang (Greenhouse)
Pot size: 12 liter pots, 1 for each seed
Germination medium: coco pellets

Listed below are the 2 potential organic soil mixtures I am trying to choose between.

Soil Mix 1 (50 Liter bag, pH 6.9): white peat, humus, black earth, mature compost, crushed expanded clay, trace elements

Soil Mix 2 (20 Liter bag, pH7): peat (45%), garden compost (20%), coconut fibers (15%), wood fibers (10%), sand (10%)


Questions:

Of the 2 listed, which soil mix would you recommend?

Is anything else needed to enhance the mixtures? (e.g. worm castings or other organic material)? If yes, how much?

Also, I already have some organic fertilizer pellets for my vegetables, 5/1.5/3 w/60% organic stuff and another liquid organic fertilizer w 4%N 6%P. Would this be a recommended option to enhance the above soils?


Looking for a simple, straightforward solution, nothing too fancy as this is my first grow....i`d like to try and have the mixture set from the start that will last me basically from start to finish of the autoflower cycle (60-70 days).


If you can please provide some sort of % breakdown of added materials into the mixture.Thanks in advance for any help you can offer, looking forward to your advice.

I would go with the first bag and add like 30% vermicomposting (castings) and some perlite depending on how much expanded clay you've got. Throw what you have in and maybe add some kelp meal, seabird guano, and some bat guano (with high P, K). If you prefer not to use guano then I would use blood and bone meal. There are various other threads explaining various amendments around here, since I'm on my phone I can't really spell everything in the amendments out for you. With all that you should have no problem lasting through a short cycle.
If you are going to recycle the soil I would add greensand too, it's a slow release amendment that really dosent start doing anything until after a couple months

thanks ghettorigger. looks like good advice. others have been recommending soil mix 2, but thats really the whole point of my thread....they both seem like viable options as long as i enhance the mixtures with some other goodies (of which everyone seems to be in agreement concerning the additions). I `dug`a little deeper into my local growshop options and found a couple of places a relatively short drive away. One shop carries the entire Pralogan line and the other carries Gold Label Special mix varieties. Any advice out there for the better choice between these pre-made options? Seems like i could go straight from day 1 thru 60/70 with basically water only. Thoughts?
