Those nutrients are immediately available. Not quite sure what's scary about MG. Yeah, it's blue, but ...

The fish and the kelp are immediately available but the Dr Earth granular is NOT. That requires processing and conversion by soil organisms into a plant usable form and that can take some time.

I would put very little reliance on a home test kit. They are notoriously inaccurate. You will always test nitrogen deficient as it is by far the most mobile of the basic plant nutrients and levels will vary even by time of day and amount of sunlight!! Most professional soil testing labs do not test for it as it is so extremely variable and will almost always need supplementation.

There is absolutely nothing wrong with MG fertilizers except for their misinformed marketing approach :-) The plants cannot tell the difference between a synthetic like MG or an organic - the nutes are all delivered in the form of soluble salts. It just takes the organics longer to get to that stage. The organics just encourage a healthier soil biology. And of course if you personally prefer a more natural gardening approach - the plants really do not care one way or the other :-))

Agree with gardengal that except for the granular the others are plant-ready. Also agree on the lack of reliability on home test kits. What they are primarily testing is your faucet water.

If you want to use only organic nutrient sources then there are many available but I recommend using the ones in pre-digested liquid forms and of course you will have to apply them more frequently at first and don't expect them to act as quickly as Miracle Grow would. It is nothing to fear and works wonders as a quick-fix for starving plants

By next year your soil biosphere will be stronger and healthier and able to use the granular products more effectively. But do keep in mind that you have to keep regularly feeding your soil to keep the micro-herd healthy and alive so plan to add fresh compost this fall and again in the spring before planting. I have been organically gardening for 50+ years and always try for at least 3 applications of fresh compost per year along with my other nutrient supplements.

Ok. Thank you everyone for your guys input! I guess I may not need to panic then about my soil. I will keep trying to feed these little guys and see if they start looking better soon.
