Autoflower Soilless Organics

Growing about 20 auto-flowers this summer (joint doctor's easy ryder and chronic ryder, low life's auto white widow) outdoor and would love to hear other peoples organic soilless mixes and feeding methods for these wonderful little plants. My thought was to keep it pretty simple this year and start out mixing in an application of Happy Frog tomato and vegetable 7-4-5 powdered fertilizer, some supplemental mycorrhizae from a shaker, and begin to water in or top dress with bone meal, wood ash, molasses, and maybe some Neptune's Harvest seaweed plant food 0-0-1 once flowering begins. Does this seem like a relatively comprehensive fertilization plan in a sphagnum/perlite/vermiculite blend? All relevant input (tips, tweaks, concerns, personal recipes) is much appreciated.

there are crickets chirping in this this thread people

Well here's my mix:

kelp, ewc, soybean meal, alfalfa, soft rock phosphate, lime, and myco. I use promix as a base, and if I need further supplementation I use the Biocanna line, with Earth Juice microblast.

Do your research on the wood ash, that's if you haven't already; it can get tricky at times.

thanks arsenal, do you (or anyone else out there) have a preferred organic source of K? as you said the wood ash, while a fast acting source can be tricky in that it can raise ph as well. i've heard good things about greensand, anyone have experience?

My kelp is 2-0-5 and I use that mostly for K, and if needed I supplement with soluble seaweed (maxicrop). and yes I've used greensand, it's good stuff and I would recommend it for sure
