How often should I use calmag

So I use RO water and I grow in pro mix hpcc. Using emerald harvest nutrients. So since I've used RO water I was under the assumption that I should put Cal mag into every drop of water that goes into the plants feed days water days all of them. At about a month into veg I noticed that my stocks start to turn purple. Leaves look healthy and green no other signs of issues besides that. Once I switch to flower it corrects itself and the stems go back to green. So my question is am I giving it too much Cal mag and causing it to have a deficiency. How often do you guys put Cal mag in your water when using RO water. I thought about backing it off to water days only

I would say the purple is a early sign of nutrient problems, root problems, ph problems, even pests. Heat stress, light stress, or pathogens. Unfortunately lots of things cause the red stems, and it's not usually a trait. Some plants demonstrate those colors from genetics, but 9 outta 10 times it's a oncoming issue not sunburn

For the purple: as long as there are no other issues...

Are you running full-spectrum LEDs? How much PFFD?

I'm running over 1k umol/s and my plants are heavily defoliated, so I have the same issue.
I had some deficiencies and used Canna cal/mag.
I added 5ml/10L to every feeding, my leaves look superhealthy now, but the stems remain half green half red-violet...
So far that was never an issue as long as they were otherise healthy, so no sweat buddy!

My guess is it's pigmentation from the lights, and maybe some limitation of P or K intake that causes it, but that's just a theory.

Hey I'm just trying to tell the guy he's probably about to run into issues. Not attack you. I also said you could be right, but it's a small chance it's genetics vs environment, soil, nutrient issues.

It may be genetics, look for leaf issues. It's normal for purple plants to turn red. Not so much for green phenos

Otherwise healthy but purple. Unintentionally watered with very cold water for the past few weeks. My well water is painfully cold and to save time in the morning I fill two watering cans the night before and bring them upstairs. Lately I run out of water and have to water the last two with ice cold water. Bro Science?? It could be the cultivar, Banana Kush auto. I see a little purple in the other two bananas but not the whole plant. It is only 40-45 days old and filling in nice compared to it's sisters. It's even got a spiral leaf tip if you zoom in. I have every freakshow in the book with this run.
Buds growing out of leaves. Vine like plants that won't stop growing. Duck foot. alternating branches and bud sites.
The plants all look healthy and I'll get some nice buds but jeezee.
I was thinking of sending my left over seeds and a sample of the soil I used to Bruce Bugbee,or Professor Debacco's students. I'm just embracing it as a learning experience.

It's quiet normal when you're blasting your plants, believe me.
Sometimes the leaves turn full red as well, as my Gelato Sorbet did.

2 Bruce Banner Left, 2 Banana Kush right. All plants emerged within 4 days of each other. Same soil, lights, watering (except one Ice cold water) and grown in the same conditions. All different. The two Banners have not moved from that spot. The bananas were moved around. The plants look healthy so I'm not worried. Any guesses wtf is going on here. I'm going to finish the grow but I have new genetics from a different source for the next run. I'm having fun with it so what the hell.

Seeing the super elongated leaftips and the dark leaves, I might take it a little easier with your normal feedings if you add cal/mag and there's nitrogen in it.

I reduced my normal feeding dose to 50% then added the cal/mag. I'll go up to 75% and see how they do since they are on the brighter side again after two days of roasting.

If you are commenting on my pics I'll tell you I have not feed my plants ever. I did add some stupid shit like kelp and crustacean meal to the soil mix for some reason. Never shop on Amazon stoned.
Cal mag, never used it. For an anual plant (90 day or less for autos) I don't think feeding is necessary when growing in nutrient dense soil.
That's my style. To each their own.

well your pots are bigger than plants no reason to have problems,but top right is starting to yellow a little...

yea the buds are really bright yellow. Banana Kush? maybe yellow buds is a trait. Don't know. A little yellowing on some of the very tips of the leaves on a few plants. No biggie. My soil must be too strong, I just kinda winged it. I mixed old soil with a new formula and added stuff I normally wouldn't. I'm trying to get the hang of indoor growing. You have to replicate a perfect growing season on the planet earth in a 10x12 room. I should stop playing around with magic nutrients and go back to what I have always used in the garden. I will have more time for keeping temps and humidity in check. Why create more problems for yourself. The BB on the top left has yet to flower. Don't know why.

This Banana Kush vined out but then stopped. All plants 40-45 days. Alternating buds and leaves twisted around to face the light. I cut the net right in half because it was doing the Autos no good being under there. The vines on the left would be outside by now if it were summer. Hash and butter I guess.

is that freshly defoliated or do you keep it like that?

That's shortly after I tied it down and trimmed it a little. When they turned around to face the light I went back and gave them all a better trimming. I like to leave one fan leaf on the bottom as a sort of alarm. I accidently did some super cropping on one plant I could barely get to bend.
I'm also growing one upside down. LOL  Some cracks at the base are healing over. whoops.

Have you checked the labels on your nutes? I’m betting they have calcium and magnesium in them.

That song "Because I got high!". Yea.  YouTube and Amazon are great at separating people new to anything from their money. Especially when they are stoned. I bought Gaya green power bloom and all-purpose 4-4-4. A racoon got into those containers, and I swept up what I could and mixed it in with my soil. Pro mix red bag from HD. Let's see, kelp meal and crab/lobster meal. Worm castings as always. Never fed them anything yet. Whatever is going on, its different with every plant. Fun times. not worried.

The Homebrew turned out perfect! Happy New Year!!!

Those are professional growers.
If anybody wants to tell me, that they don't know what they are doing and that their plants probably are stressed and have deficiencies, good luck.
That's just FOHSE lights with I don't know prolly 1500-2000 umol/s kickin some energy into their plants.

Reverse osmosis removes impurities and dissolved minerals, so it has low or no buffering capacity. Buffering capacity is the ability of a solution to resist changes in pH when an acid or base is added. Reverse osmosis water has low buffering capacity because it has little dissolved minerals, so the pH may change more readily when an acid or base is added. However, it is generally safe to drink and may be preferred for its purity.

Calcium is a good buffering agent in many forms so I'd add it. PURE RO can cause you to chase your tail due to the rootzone pH being fucky.
