Women are so hard to please...tox/def inquiry

Hey Ya'll

I have been noticing some necrosis/yellowing on some leaves on my 3 ladies. It isn't a major issue as most of the plant seems to be doing just fine, but I wanted to scout for some opinions as to what is going on here.

I've consulted the leaf def/tox chart and this seems to be a combination of what I think is K & Calmag deficiencies. I'm not 100% on this so I'd like some feedback!

Medium: Promix HP / Dr Earth 4-4-4/ EWC
Lights: Mars Hydro TSL2000 - 50%, apprx 20in, 19/5 - I have been raising/lowering based on how the plant looks. Decided to lower them recently after some much needed defol uncovered some nodes that were underdeveloped.
Environment: Light on 80f/60rh Light off 70-74f/65rh
Feeding: Feed/water/water/Feed - EC- .9-1.2
Nute: 10-3-6 on feed days. I added 1/2 strength calmag only twice during this grow so far (separated by two weeks). Added some Lotus Bloom 1/3 strength once just to boost pk levels. I also did a Dr. Earth 4-4-4 tea about 1.5 weeks ago to boost the microbial life, and added some molasses a few waterings after.
Strains: Bruce Banner, Skywalker OG, Black Widow

Misc - added nematode SF as preventative for gnats

Any help is appreciated gentlemen!

Thanks!

PS - The one with heavy necrosis is Bruce Banner

Nutes/misc for reference

Info From previous post:
Lights are probably a little too strong as I noticed some bleaching on upper growth - you'll notice a few holes or gaps on each plant - trying to jumpstart the growth that was hidden before I defol'd. The necrosis is really what bothers me - I'd be happy if it was a nute def/tox. Hoping its not due to critters

I have this exact same thing going on except it has not happened until flower and it is killing the plants. My plants in question are Deadhead og fem auto. I have never throughout the years had this happen but also my first auto fem run in ever. Also my first time using anything other than natural living soil.. Kind of interested in what people think of your situation because it seems no matter what they are gone as soon as the spots start for me.

Check out this thread I made in a diff sub forum looking for the same answer. It looks like some people are suggesting a pH issue - see padawanwarrior and Budsbuddha's replies

Is there a Doctor in the building?

Hey ya'll Having some adverse reactions to something with my lovely ladies. Noticed this on all 3 plants, a little worse on the bruce banner. Not quite sure what exactly it is, I'm thinking it has something to do with potassium or cal/mag def. What's the prognosis, Dr. Greenthumb? Medium...

Yeah, it is getting the pluck today. It just got that bad over the last 4 days. It was just spotting like OP so I did a flush and half nute and it went fast.

Learn from it,i would do a soil ph test just for kicks.
 
I have never had issues like this before but this is also my first time using store bought soil (FFOF). Usually I make my own of all things I drag in from the forest and my compost pile but I have no compost pile that I can use as I just moved and I just started my new pile. I'm probably going to switch to DWC until I can start making my own proven mix again.

How about EC of runoff water?Have a good look at roots and smell when you dump it.Crazy that a plant can go to shit so fast.

My buddy uses ff cultivation nation and its MUCH stronger than your stated 0 5 4! You fried your plants. Cut off all the dead and damaged leaves. Flush with water and just feed worm casts tea to help decrease the chances of getting harsh smoke when dried.

I tested runoff and it was 6.3 but I have had a very poor experience with using FFOF mostly because I am used to making my own soil that is alive. I'm just culling the plant but the roots don't smell bad and when I flushed some were exposed and looked fine. I don't think it is root rot since I don't heavy water. I just water until about a 10% runoff and then wait until the plants show the need and or my soil starts feeling dry a knuckle in. I have been growing for 20+ years and never experienced this before so it boggles the mind a little.

Yeah. Would be nice to know though why. Buddy above may be on to something and it was a PK overdose??
 
My buddies fox farm cultivation nation he uses is like 0 30 20. Very potent.
If you haven't culled it, prune the leaves and give worm cast tea/extract. The casts are really like a tonic for sick, stressed, or injured plants. And even with healthy plants adds quality in terps and milky trichs late in finish.
 
Just culled it a few mins ago to make room for more flowering plants. I did snap pics of the roots. I do have a large bag of worm castings!

Try make a tea or extract for the healthy ones. It can really bring on trichs and gland swelling. I will use it instead of plain water at time instead of molasses solution. It will not burn ever. Casts extract are also an effective treatment for powdery mildew as well. Just soak the plant till just run off of leaves. All surfaces. Like most organic treatments coverage and volume used are key to making them work.
