calcium deficiency,lockout?

so this morning I've noticed about 30% of my leaves have obtained these little brown spots over the past couple days and I think its spreading I've checked very thoroughly for bugs or spider mites and there doesn't seem to be any of them, the reason I think its lock out is because I've been bad about pHing my water after I mix my nutes and also never check the soils pH. I will do that tonight though. The reason I think its calcium is because I have never given the plant calmag at all and the nutes I have been giving it (to me) are still kinda high in nitrogen.
The plant is week 5 into flowering its amnesia haze auto and its my first grow the soil is happy frog with 30% perlite in five gallon smart pot
its under an Apollo 300w led
and the nutes I have been feeding are
general organics go box line
advanced nutrients b-52,bud candy
fox farms tiger bloom
I usually feed her every water and give her just under a gallon of filtered water my usual mix is
go bio bloom-8mls
go bio bud-2.5mls
go bio marine 1ml
an b-52 5mls
an bud candy 6mls
and once a week I throw in 9mls of tiger bloom ill take anyone's advice or input thank you!

I think you have a couple issues. Ph is off. Plants need cal/mag probably and I believe they are starting to show nute burn at tips.
yea checking the pH tonight will tell me alot more I plan on doing some lighter feeds but will add calmag and see if it helps

Hey OP you and I have the SAME looking problem. Most people have told me to check my PH and make sure she's getting phosphorus. Please report back here if you can? I am interested in if this gets solved. I've basically been watching my PH and adding LIGHT nutes cuz it looks like I lightly burned mine too, and adding Cal/Mag as well.

Adding cal mag won't fix the problem stabilize the ph then dose them so the plant can take it in immediately easy fix as for the nute burn I push my plants to the verge of burnt tips then dial it down a notch

I watered my plants (soilless) in 5.8. Is that too low? Should I boost it up to 6.5 in the future?

checked the soils pH and its right at 6.4 which I guess isn't too bad I thought it'd be alot worse i have never given the plant cal mag before you think giving it some still wont do anything? What if I try taking nitrogen and potassium down

If your PH is correct then I would say hit it with the Cal/Mag, I think Budgoro88 was saying to fix teh PH (if there was one) first.

yea ill throw some in her next feed tomorrow can't hurt to try it
Good luck buddy, I have the same prob as you so I hope we get this figured out. I used to think it was a PH issue as well, but I checked what I was giving them and everything seems to be on the level. I kinda think I just transitioned poorly into flower, and I also think maybe the air is hitting her kinda hard. But now that I know our PH isn't off, I really think it's a Phosphorus def and maybe a lil Cal Mag as well.

I meant to ask you, why do you "fluctuate yours from 5.5-6.8"? Do you do that on purpose? Or you just saying as long as yours is in that range you'll throw it in? One last question, my water PH's to 7.6 without adding anything to it. I was able to feed my babies, and my vegging plants all the way to flower without seeing anything bad happen to them. Is 7.6 not THAT bad then? Or could the lil bit of dolomite that's in my HF be Ph'ing my wa-wa? Sorry to throw so much at you.

Give it cal/mag. Your plant needs it and the micronutrients in it.

I fluctuate it cause the intake is different at different ph people prob get same results as me not fluctuating it but for my own mental peace I've been doing it for 10 years that way when I see a sign of deficiency I adjust the ph to a level that promotes maximum absorption of that specific deficiency and it's always worked. As for your water it all depends on what nutes you use once you add those it will change again. Mine is 7.0 I water with that no problem

Well, it looks like my PH is alright. Idk what could be causing this...the only thing I can think of is, it's just normal. The flowers keep growing, the top looks healthy AF, it's just the undercarriage, under my ladies skirt where little, older fan leaves are shriveling like an old man's nut-sack.

wanna know a secret?

n od, locks ca.. high ca concentration will then bind with soluble p creating an insoluble calcium phosphate in yer soil

alot of problems go hand in hand, you have one, youll have a few others too

dont forget you can always foliar feed...

this is why I suggested if should take my n down I've heard high amounts of k will lock out ca as well
