I'm glad you're taking it all as 'advice'.
I know you're going to hate to hear this, but looking at the pic puffy posted, that looks like a K deficiency, reminded me what he said about only .1 below the PH range for calcium.
After thinking about it, and how infrequently anyone mentions a calcium deficiency, I think you have a K (potassium) deficiency, which coincides with the .1
Sorry, IDK why I didn't look closer at the pics you put up when Grindin said calcium, but I'm going with a K deficiency, and you say you're still vegging, and only fed once, with 3-5-5, which isn't much at all, for the size of that plant.
It is probably putting everything it's got into trying to build a rootball to fill that newish looking home.

so did we figure this out yet?? i have one single strain showing the exact same thing. none of my other strains are doing it, but two diff seedlings from the same strain are doing it. ive grown for a while and not seen these spots. i thought they were bugs and i was like o no! not bugs tho... i was told maybe cal mag, especially if N is low. but it happens more in flower like that, mine are in veg. i was also told that it could be genetic, but im starting to doubt that in my case.

Ok, just got home and took a few pics of the current conditions of the leaves, so you suggest it might be a potassium deficiency? Since I started using nutes, i've been going with the 20-20-20 ratio about once a week, but stopped giving that about 2 weeks ago because of this browning problem. Should I continue back on the 20-20-20 feeds?

Take a look at the photos, maybe it will be more clear for your examining. Again, thanks a bunch for all your suggestions and comments!

Current Nute Info: (Dec 24)

Nutrient mixed solution pH level: 6.5
Nutrient mixed solution ppm level: 320
Nutrient Mix: 10.0-2.0-9.0 mixed into 1 liter of condensed solution
Water type: Tap water (changed from distilled water)
Tap Water original pH level: 8.4 (mixed nutes into water and pH'ed the water down to 6.5)
Tap Water original ppm level: 72 (mixed nutes into water and now ppm level is at 320)

Previous watering/nutrient specs

Distilled Water original pH level: 7.0
Distilled Water original ppm level: 2 (two)

Hey Guys,

Shits getting pretty serious here, really need some help!! The leaves of the plants went from probably 10% "brown spotted to brown to yellowing" to about 30% now!! I flushed it 5 days ago with pH water at about 6.3-6.5, and then re-nuted it 2 days ago with natural tomato granular nutrients (i soaked about 15grams of the granular pellets "9.0-2.0-10.0" in water and mixed into half gallon of water, then pH'ed it back to 6.3-6.5) and still no luck. I thought it was a cal/mag or potassium deficiency but still looks pretty sick...

Look at the pics and see if anyone can help! Thanks and please hurry!!

Doug

Check the PH and get those very dead leaves off there because that's where mold starts.

yea cut that shit off man. you can see your newer leaves in the pics and they look beautiful. sometimes the plant will use valuable time repairing shit like that.

and i see perlite. liar.

HAHAHA, that's not perlite, its tomato granular nutrient pellets... but anyways, i did some research and they say not to cut off the leaves because they're providing the missing nutrients for the main plant... but it will cause mold if I dont take it out?
