This, and also Ignignokt's mention of air circulation are valid points. Has there been a change in the Temp/RH balance lately?

Unstable medium. Looks like too many nutrient salts, and pH issues, leading to twisted leaves and nutrient lockout issues.

I presume you mean KIS Organics?
KIS Organics Veggie Soil Mix

Ingredients: Sphagnum Peat Moss, Coco Coir, Pumice, Composted Fish, Earthworm Castings, Kelp Meal, Crustacean Meal, Alfalfa Meal, Basalt, Oyster Shell Flour, Lime, and Gypsum.

KIS Organics Water Only Soil Mix

Ingredients:Alaskan Sphagnum Peat Moss, Oly Mountain Fish Compost, Earthworm Castings, Volcanic Pumice, KIS Organics Microbe Catalyst, Gaia Green Canadian Glacial Rock Dust, Cascade Minerals Basalt, Calphos Soft Rock Phosphate, Pacific Pearl Oyster Shell Powder, Organic Alfalfa Meal, Organic Fish Bone Meal, Organic Crustacean Meal, Acadian Kelp Meal (ascophyllum nodosum), Ahimsa Organics Neem Cake, Ahimsa Organics Karanja Cake, Organic Fish Meal, Organic Feather Meal, Organic Steamed Bone Meal, Natural Calcite, Ag Lime, Mycorrhiza*, and Beneficial Microbes.
Forget about the Iguana juice or anything else.

Flush, and just give them a light bloom food (P) so that their roots can grow into the already fertilized soil. And just a touch of epsom salt throughout the grow for sulfur and Mg.

I have had bad experiences with added peat. Leaves would become like paper. Almost white. Thought this was ph too low.

You are overwatering, have too much accumulated N, you need Ca. I would say your Na and K are off the charts. I wonder about your P.

Can you measure runoff? Do you have a conductivity meter? pH paper?

I would wash with 10% solution of low fat milk. And then no more water til they ask for it. Sure would like to see the conductivity and pH though.

The ideal thing to do is send a soil sample in real quick to the lab.

The rest is called best guessing. And as you can see from the broad response, everyone is taking their best shot at it. At the end of the day, science can save the day.

One last question, is your soil mix staying wet forever?
