Kinda going through this myself in week 5. I have determined with some help, that this is a K toxicity, which can lock out CA and MG. I’ve flushed one today with 3 times the pot capacity to see if it sorts itself out. After it dries out, I’ll continue the feed regimen.

That was around when mine started and i tried to flush for about 2-3 waterings and think they maybe made the cal/mag issue worse
 
not really any improvements if anything they may have gotten more yellow since feeding them i dont really know if it made it worse was saying maybe since i didnt feed them for a week that they needed it and was not getting it

Prob the case. Did you do a very heavy clean flush?
 
Stop flushing ..... all you are doing is exasperating the issue , when you “ flush “ you LEACH ( strip ) the medium.
That is why it is getting worse. Bump your PK and give those flowers a chance .

Those plants are lacking in potassium ( yellow edges )

Hey @Budzbuddha .... The only reason I came to my toxicity conclusion was that K is a mobile nutrient, and my lowers are not affected at all, just the tops.. Been feeding every time since clones at 1000-1100ppm with (after the flip) Tiger Bloom at 500ml per 50 gal, Beasty Bloomz at 68ml per 50 gallons (0-50-30) and Rasta PH up at (0-0-35).. that's alot of K.

ment dabber guy plants ( p issue )
 
I am terrible at keeping track of everything been writing what i do down now so i can go back and see what plant got what when instead of guessing. have a few dif strains going and keeping track of what got fed and what didnt was impossible with the amount hopefully writing stuff down will help in the future.

I would shit can the beastie , I would use once around week 6 and that’s it. It was way too much. There is some nitro excess showing too. Notice the dark shiny leaf. Excess in one element interacts with other ( antagonism ) elements.

Yes sir.. got the Mulders chart from Renfro. Great info!. And yes, I do have the dark shiny mid to lower. Not all of my strains have been affected. Orange Kush seems to love what Im doing, but Dosi Whao!, and Kosher Sorbet are struggling with the toxicity. OKC is going to be a keeper for sure. She's a beast. Early Lemon Berry is doing ok with it too. Dosi has been the hardest strain I have ever grown.. Everyone loves it tho, and I want to continue that strain for the Fall run. This is the 3rd run of all of these strains from clones. Kicking out those weak strains and introducing a couple more from Ethos .... we shall see.

In my opinion, neither case here is a P or K toxicity. The chattered, yellow leaf margins, in both examples suggest you're short on K, which wouldn't be a surprise being you're in flower. As noted the leaves won't repair themselves, but you can subside any further affects. I'd make sure your pH was dialed in, I'd look at what I was feeding to be sure you have room for more K in their diet and if the pH is right and you have the room, I'd up their K. Good luck to you both.
