I don't know what a slurry test is.
How do I perform a Slurry test?
This test will give you a general snapshot of the current conditions of your medium. Wait for your medium to dry out in the top 2”. If you just fed, it is not dry enough for this test. Wait for it to dry out. I can't stress that enough. Don't try this test with a wet/moist grow medium. Take the sample from the side of the pot, 2" down to keep from disturbing the roots too much. Obviously if you dig deeper than 2”, you will want to ensure your growing medium is dry at that depth as well.
It's a 1:1 ratio grow medium to water. 1 ounce to 1 ounce, 2 ounces to 2 ounces or 1/4th cup to 1/4th cup. Most Nectar growers are using one ounce of their medium to one ounce of pH neutral 7.0 water. If you don't use 0 ppm water, you need to subtract the ppm of the water you use to perform the test, with your final ppm. For example: If you use 25 ppm water, subtract 25 from your final slurry ppm. Once you have mixed your grow medium with pH neutral (7.0 pH) water, let it sit for 15-30 minutes to stabilize before inserting your meters.
Immediately prior to inserting your meter, give a good stir using a glass stirring rod or some other clean instrument. Using an EC/TDS/ppm Meter, ensuring that the meter is inserted into your slurry to a depth that will give you a correct measurement, measure the ppm of the slurry mix. The purpose of this slurry test is to check ppms to see if your plants are efficiently eating. With Nectar for the Gods, numbers above 500 means they are starting to not eat (salt buildup). Above 900 they are not eating, they are pissed (time to flush). Below 200 they are eating and are hungry (bump up the feedings a little). Below 100, your girls are starving (bump up the feedings even more). Between

[don't change anything if your plants look happy] At this time, you should also do a pH test on the slurry (most people do both ppm and pH.) Stir the slurry mixture and insert the pH meter fully into the slurry mix. Write it down, post it on the Growers page for additional feedback. “Nectar for the Gods performs best when the medium is in the pH range of 6.3-6.7 and the ppms are between 300-500." If your soil sample comes out with a lower pH and/or a higher part per million, then a flush with Herculean Harvest will help correct these issues.
here you go this come from the NFTG bible i hope it helps
Symptoms i see are magnesium and possibly potassium as well..i dont have experience with true organics, so unsure of how to help other than add some epsom salt (for the mg), and organic unsulphered molasses (for everything else plus high potassium)...raw coconut water is also good for potassium and natural plant hormones like cytokinins!
