Brown Spots ? Does anyone recognize this ???

Of a sudden out of no where I get these brown spots , mainly on my younger plants. Does anyone know what for sure it is? The only thing I did different was the source of Water, and I already knew it was going to be higher in PH because it says so on the front of machine. So I get the 5 gallons refill and I don't have any calibration buffer for my WATER PH Stick , but I have the soil PH thing to use. I add some Apple Cider vinegar to water w/ nutrients ( it is possible may be to much I used an Organic soil to my mix that I don't normally use, I make my own kind of soil that's usually bomb))) anyways next day or two THESE BROWN SPOTS AND TIPS , mostly on the babies but a few on the Older girls ....any ideas ??? I flushed 2 of my babies and added more cider vinegar. The SOIL TESTER IS SHOWING above 7 . I don't have many pics as I removed them in process of trying to heal them but I post what I can, and as you will see it's mainly my young plants . TY

Soil PH of 7 is a bit high, cannabis usually likes it 6ish but I doubt that's causing your troubles. Maybe some of the batches you PH'd were off but it'd take a lot to hurt them and you'd have to be doing it for a bit. I doubt you'd have gotten this far if that was the issue.
Your last pic looks good so it's hard to say you're doing "this" wrong. I'm not sure what's up with your other plants. Here's a link to a guide that'll help you https://dutch-passion.com/en/blog/a-visual-guide-to-cannabis-deficiencies-n987
Somebody else should be along to help you out.....

Yes your exactly right!!! I moved to this apartment and found a Water Machine at the local Circle K , so I can fill up my 5 gallon water jug. I had noticed it said on the front of machine " higher PH , vitamins and minerals added,""" It didn't think to much on it and figure ahhh it's probably 7 1/2 , I will just throw a cap full of Apple Cider vinegar in it and be fine , well come to find out it's actually like 8.8 pH ...I am slowly getting them back to good health , of course I had to flush them, so now it's over watered , but I pulled most soil out from all around roots without damaging, and letting soil dry out on cardboard . Thank you for replying , I posted a few days ago hoping someone could help confirm what I was thinking to so they will receive the right help ASAP. ALOHA AND HAPPY GROWING...

Yes I have the PH testers , but ran out of the calibration stuff , so lately just been using the soil pH tester and keeping her just under 7 , U know it's not very accurate but I have to wait till payday

I like to hang around the unanswered posts section. I hate it when new people post and don't get help with their plants. I get to meet growers like you.
Aloha yourself @BigfootsCousin

Right on TY , I am not really a newby but I am also not a Veteran grower lol, I grew a couple times out door in Hawaii , now I live in Hot , Dry , Arizona and this is my 2nd grow indoors from seed. My dad was a famous grower back in the 60s and 70s I heard from people , so not knowing him very well growing up ( divorce) , after he passed away from Cancer ,I decided to grow and try come up with good strains to help people with pain and cancer. I do slot of reading and studying , a lot of listening and A HUGE HELL OF A LOT experimenting ...so far going good , last indoor did fairly well after killing about 6 plants Bahahaha , not used to lighting and all indoors and over watered, over nuted and over Luminary . Haha....Peace , stay in touch

Looks like calcium deficiency from those little burnt brown spots. The last two pics look very nice though.
