Potassium Def or Over Fert? Help appreciated (pics)

[Iron_Lion]

So whats your thought? Satori in soil, pH adjusted 6.5 fed pure blend bloom,
fox farm big bloom, liquid karma, cal mag, molasses. I thought it might be a potassium def so I fed a little big bloom, fox farm cha ching 9-50-10, cal mag, and molasses yesterday. Over all plant looks very healthy, green and budding up nicely, no leaf clawing, or burned tips, just a few of the oldest fan leaves look like pictured.

I should mention, problem appeared about 5 days after prior feeding, thats why I think it might be a def of some sort. Plants are on day 39 12/12 and I havent changed anything, same ferts, same pH. I usually feed every 8-10 days.

That is the first time I heard of FF cha ching and I Would not be using it; it's way to strong and not balanced enough for cannabis, too much phosphorus.

So you fed them the problem may be due to your feedings, what is the dosage you are using?

Can you fill this out so I can find out more info please? You should not be having any deficiencies unless you are not feeding often......

but it looks like there is more of a lockout issue going rather than a deficiency.

WHat is the amounts you are using of your ferts, how much per gallon of water and how often are you feeding?

this is my second run of this strain, all plants fed same mix, other strains look great, no sign of disease, pests, deficiencies and over ferting. Cha Ching is a blossom booster, I wasnt sure if just the big bloom and the pbp bloom was enough for flowering. i've used cha ching before with no harmful side effects.
plants have also received pure blend hydroguard a little over a month ago. Do you think a flushing is in order?

foliar feed the leaves with 7-10ml a gallon of pbp bloom, keep on your usual nute scheme or increase the amount or frequency of feedings. if it doesnt stop or clear up in 3-5 days, flush them with ph'd water and see if the problem gets any better.

are the upper leaves folding inwards at all? the edges of the leaves?

I think you should have more like 40% perlite. Im guessing your problem is nutrient burn or just the natural dying of older leaves as harvest grows near.
