Am I a complete idiot? What in the hell do I keep doing to cause this?

I swear I’m just lost. Seems like all my plants keep doing this. So obviously I have a huge problem. Ph is in right at 6.5 during water feedings. I use Ph perfect advanced nutrients sensi a and b. My tap water is around 170ppm so every other week I’ve done a light calmag feeding. My room stays above 70° even when lights are off. Lights are a 450w cree cobb and it’s way above the canopy. Watering when pots are light. And look at this shit. Every plant. Purple. Growing in “organic” natures care soil”

Ditch the calmag. More than enough in your feed and tap water
Calmag is for ro
Once a week @ 500ppm isn't enough. The other times you are using just water?
Are you using the calmag full strength?
If so you're soil is bunged up with calcium locking out phosphorus hence the yellowing and purpling on the inside part of the leaf blade.
I duno that medium. I tend to stick with things that have been proven to work well for cannabis.

I'm a coco grower so I may be unknowingly blowing smoke, but 500 ppm once a week sounds to me like they're starving. Again I'm coco so I could be WAY off, but I feed up to 1000ppm in prime flower every other day. Is your soil really making up that difference? I use different nutes so that is one factor. Just an outside opinion. Happy growing!

You should be feeding coco daily.

If I were going for more than personal use and gifts I would absolutely agree, but I'm in tents and prefer to keep them more manageable for me. For example, I have a near pure sativa that after just 3 weeks of veg, I HAVE to move her into the flower tent she's already about 20"tall, after LST, and she's going to double that in flower. So I need to keep them smaller to keep them out of the lights.

Man from what you have just said and previous conversations I think I have too much calmag. I need to throw that shit away. My soil also seems a bit cold. Which can lock out phosphorus too right?

I wouldn't worry unless it's colder than 65
I duno that medium, it could have a bad ph or it could lack buffers and the pH is swinging. I use ro and I only add 1/3 the amount of calmag otherwise I'll get lockouts. If you got 170ppm tap water that should be more than enough calcium in there
