Relatively new raised beds often lack the active soil micro herd required to sufficiently convert solid form organic materials to the nutrients needed by the plants. It takes time for the herd to develop.

Weekly does of compost teas as a root drench, assuming good quality, highly diverse components, compost can definitely help but IMO aren't enough. Additional organic liquid supplements are usually a great benefit to the plants. Especially so when it comes to micro-nutrients.

There are many high quality liquid organic supplements available. The choice is yours. They can be mixed with compost teas or used alone on alternate schedules.

As for a "schedule" of fertilization using only organics, the Organic Gardening forum here would be your best source of that info. I fertilize with organics but I use fertigation so have no "schedule". Those who use synthetic fertilizers usually recommend a 4-6 week schedule but that doesn't work with organics.

Great info, thanks Dave.
