Is my Super Soil mix killing my plants or is it something else?

This is the soil I used, it has Kelp meal in it.


What follows is a copy and paste from this thread
My first mix

I used roughly 5.25 cubic feet of that with about 1.75 cubic feet of organic "Just Coir" (Black Gold). I added some pumice as well and I used 20 quarts of worm castings. Another ingredient in Roots I was lacking that I was able to grab was feather meal, so I added just under a pound of that to he mix.

My numbers are as follows
Bone Meal - 3-15-0
Rock Phosphate 0-2-0
Blood Meal 13-0-0
Guano 10-3-1 (was unable to find "bloom" guano, but I figured it was better to have it than not.
Humaric Acid Powder w/ potash 0-0-10

The place in town that had Azomite would only sell it in 44# bags so I bought a pound of Glacier Rock Dust for .40. Was told it was just as good if not better.

Id like to know if you all see any problems with the substitute soil I used and if my numbers are lacking in any areas. Perhaps low on K? Thanks for all feedback given.

My mix sat for almost 60 days before I used it.

I asked if my mix was low in K and nobody thought it was an issue, got more comments about the N values being too high. I imagine I can just throw down a layer of SS on top to feed them what they need? They are 40+ days into veg and I will be flipping the light on Thursday. I also plan on brewing up some beneficials for my next watering which should be around then as well. How else could I add K to the plants organically if you guys really think I need it?

It's a week later and the plants are doing much better, like the burning never happened. Back to growing a few inches a day. Feeling good about the work again. Thanks for all the help.

What kind of water are you using?

Tap, aerated 24/7, and as I said above, I suspected something about the res I was using. That has been replaced.

Do I need to add K to this mix? New growth is good right now, they are loving life once again...
