Freckled Yellowing Leaves - K/Cmg def?

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!

looks like a mix of not enough food,should be dark green.Stick with one food,so 5 gallons promix add 1 cup 444 mix and plant.top dress every week 1tbls per week+ewc say 2-3 cups.Lime already in PM hp and in 444 so no calmag.
For a quick fix now some fish hydrsolate like 2-3-1 or more N like a 5-1-1. will help.Or even some salt food at 1EC will work quickly.
 
re read what is the 10-3-6 ? That should have green them up?
perhaps light too strong?

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

10-3-6 is from the local shop Whitney Farms brand. It has 3 cal and 1.5 Sulphur in addition to the npk

Daytime temps are 80-81f. Dips a little at night, naturally.

The 10-3 -6. What is it? Salt food organic?

Oh! I'm sorry, yes it is organic powder/salt form

Ok u said around 1EC you feed so has to be water soluble salt stuff.So mixing the two ,organic and salt, has messed up the balance.
I like to stick to one way/kind.
The pics show a lot of yellow, which is why I say shes hungry.But could be a toxicity with the mix you gave her blocking everything.
I know the pk boost stuff didnt help,it never does lol.
Id mix up your salt food 1EC and feed to a healthy runoff 1-2 gal min.Wash out the old start fresh.
 
Also the 444 tea and molasses probably crashed your ph,it happened to me, yellowed overnight.I quit that stuff,
Any who, just rambling off stuff that it might be.

I appreciate the help brother! Thank you for the advice I will take all of it into consideration.
 
After consulting these two charts, I believe I have narrowed it down between a Potassium def or a Manganese def

What do ya'll think?

Spray them down with some Epsom salt, then when you water or feed them again, add 1/2 tsp of Epsom salt per gallon to the mix!
