Not sure what’s happening

[Abbazabba85]

Leaves are turning a copper color. I’m in happy frog with Gaia Green 4-4-4 and worm castings, weekly cal-mag watering as well with a flat 7.0ph.

Im no expert but i think you have classic nute burn from too much calmag, i only fed mine once during veg, in fact i grew in plagron batmix and i couldnt go anywhere near it with nutrients for 4-5 weeks because the tips would start burning

Looks like they're getting too much P & K.

 

[RootFarmer]

Looks like excess magnesium. It can impede phosphorus and potassium uptake. Excess magnesium can even cause symptoms that look just like magnesium deficiency. When out of balance with calcium it can lockout calcium. Calcium is essential to pretty much every function in a plant. It affects the uptake of all nutrients. Go screwing with your calmag ratio and everything else gets thrown out of whack.

No, it’s not excess. It’s actually a deficiency in magnesium.

LED lights these days are incredibly powerful OK and even at lower settings some strains tolerances can butch a whole lot in veg so a lot of the time just through the output percentage and proximity of the lamp with some strains. It will cause them to pull all the magnesium out of the soil almost overnight. It’s a very common issue. I deal with it on a regular basis and I generally don’t care about it as soon as it starts happening I’ll just start adding a little bit more magnesium with epsom salts and table spoon a gallon would be good here. And then once it switches over to flower the demand for magnesium stops completely so no matter what once you flip the problem’s gonna stop as soon as you get to the stretch phase, anyway, but that being said you should still triage in the interim, you need to turn your lamp down the output is too high for that plant in particular and a tablespoon a gallon on salts
The damage is already occurred is not gonna go away so you just need to monitor new growth and ensure that it stops oh and also on top of everything I already said that you need to do go ahead and try to hide the plant behind a bigger plant for a little while, because basically the plant can get over it before the whole flower thing I was talking about if you hardened it off like you would any plant outside, you put it under filtered light and the stresses become Less so that’s another thing that you can do to help put it on the outer perimeter behind a larger plant

And the P and K deficiencies?

And the P and K deficiencies?

The plant is in vegetative. There’s literally zero demand for either one of those yet.

Thanks for the input, I started them on a Green Amino/Natures Brix water in supplement once a week, guy at my local cultivation shop said it was good for cal/mag issues. I will dial my lights back, its just wild because I have this issue in 3 separate tents with different LED lighting in each one.

If they’re not all the same strain, it’s highly possible like right now I’m running 12 different strains right
I have four different strains, pulling mag myself, man. And near the damage that has occurred won’t fix itself. Some of the fading in color may get a bit more green but other than that just monitor new growth. When you flip to flower it’ll stop anyway magnesium demand stops and flower completely basically
Its some thing that happens alot under these lights. Heres a plant now and peep my setup, high lights at 30%
It just comes through with the territory, you know, and I preach it all the time and even I become victim to the shit too, but you know you always start with everything on the output side of your lamps, low and hang them as high and if your plans demand more from you in terms of light boost that individual plant up towards it Allowing all the rest of the plants to chill out and carry on

 

[Abbazabba85]

For sure, I have 3 different strains with the issue. All my lights are pulled up close to the tent ceilings, but I will definitely turn them down more.

I agree with this, I discussed with a local grow shop near me. I’m in coco. They require the neuts, all of it every time you water. So you’re probably looking at deficiency. I’ve upped my feeding schedule from every 7 days (not including watering) to every time I water. It seems to have made a difference!

 

[Jr123456]

I would say your PH is a little high, I’d aim for between 5.8&6.4 if you can. Might aid with plant uptake.

Yes, turn your lights down. If your plants were healthy, you would probably be ok with the lights running where they are at but right now we're experiencing nutrient issues. Yes, I agree that its related to cal-mag use during veg. Your plants look like magnesium is being locked out in some of the pictures while potassium is being locked out in some of the others. Calcium is well known to interfere in their uptake. It's far more common to have excess calcium causing issues than excess magnesium. Although the response was on point IF you were giving your plants super-sized doses of magnesium. Since cal-mag was mentioned, its more likely calcium locking out the other nutrients and not magnesium.
