Reminds me of magnesium deficiency the way the veins are green but it's yellowing in between and it looks like it started in the middle, not the top or bottom. I'ma vote magnesium, hit it up with some epsom salt if you have any.

What's the pH of your soil, and what is the pH of whatever you're watering it with??
I strongly recommend foliar feedings of epsom, since it's too easy to mess up your soil with excess mag. Your cannabis flowers should not spark and crackle when burned, even if you clip some at the peak of flower.

PH is around 6.5 for water and soil. I have suspected magnesium and treated for such. Good quality soil and nutes. It is spreading fast thru the room and does not discriminate between the 4 stains in the room. From a few plants four days ago to about a third of the plants today. It started with small plants, about 6 inches tall and spread from there at a alarming rate. I believe it came in on the seeds for the 6" plants but just guessing.What's the pH of your soil, and what is the pH of whatever you're watering it with??

I never would have though magnesium you shouldn't run out of magnesium in decent soil until maybe well in to flower and that's only if your pH is slipping or you have no dolomite or organic matter in the soil..
I'd suspect it might be pH related probably.. and/or having had amended the soil with too much or too little of something..
Can you tell us some more details about your soil and environment?
It's not a fungus.

I'm of the opinion that 90% of all problems in the infirmary are pH related. That's just like, my opinion though man. Magnesium shouldn't be locked out unless he's below 5.8 pH in soil, and he says he's inputting 6.5 but maybe test the run off too AKDRUM. Good luck bro.Soil is Kiss Organics. I amend with a bit of gypsum, peat, sand and pumice. Once plants are large enough I amend with kelp, neem meal and malted barley.I use some Iguana Juice every week. Room runs about 75 deg. and humidity runs 40 to 60% but try for 45%. Light cycle 18-6. PH seems right 6.5 and does not fluctuate much over time. Plants 2 months old about and 26" tall.Looked great until about a week ago.
Yes not a mold but perhaps a fungus. Started treating with Green Cure and Exile to see if that works. Seems to be helping so far, will know in the next few days. Also foilered a couple of plants with a mag. solution to see what effect that might give. My first thought also was a mag. issue and gave a soil drench but did not help. Perhaps it was not strong enough, being careful with Ferts.

Not sure if your running a dehumidifier but my plants that are right next to mine literally look identical to your photo. Could just be a coincidence and probably is but I just figured I’d mention it. It’s only one or two plants right next to the unit itself that get direct air blown on them from the dehumidifier

Air circulation?

This, and also Ignignokt's mention of air circulation are valid points. Has there been a change in the Temp/RH balance lately?[FONT=Arial, Helvetica, sans-serif]

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?

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.
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?
