Over watered or magnesium deficiency?

[IFukup]

I'm guessing over watered or magnesium deficiency. Or could it be something totally different?

 

[Gmix]

I dunno bud I keep wondering if your lights to close also looks like your nutes are inbalanced.

I’ll see what others have to say

Mag deficiency

 

[rangabud]

Not over watered, but what nutes are you using? And what strength?
Also lights and how close are they?

We need more details mate. Also is that a 2x4 tent?..and what size pots? buy epsom salts..mix with warm tapwater...it's hard to overdo espsom salts as a foliar...mix around 1-2 teaspoons per liter and foliar feed them in the morning and at night..do the entire plant, but focus on the bottom of the leaves, as that is where the majority of stomata are.

Def need more info - nutes water ,lights, soil, run ….. the more the better

Plants are in 5 gallon pots. Using living soil with just gaia 444... Lights are 30 inches away on level 2 with AC infinity controller. Coast of Maine with worm castings with 444 @ recommended dose. Gave dose of Epsom salt but didn't dilute in water just to coated.

Magnesium def

Foliar feed, foliar feed, foliar feed epsom salts...and start giving 1 gram of epsom salts per gallon. They look nice and happy, it's an easy fix, alot of organic nutrients are lower in magnesium, with them assuming your growing in soil, which naturally has trace amounts of magnesium. Cannabis however, loves magnesium, so you sometimes have to supplement, some varieties being more hungry than others.

This threw me off mate, what do you mean "just to coated" Avoid epsom salts with additives like dyes and perfumes,etc.

Foliar feed in the morning? I wouldn’t do that. Spraying just before dark prevents the magnifying glass effect of droplets burning the leaves.

Apologies...i top coated the soil with a tablespoon of natural epsom salt couple days ago.

That will help, but a folliar feed of 1 teaspoon per gallon of distilled water and sprayed on the leaves under dimmed down lights will be the quickest way to get magnesium to the leaf.

Magnesium deficiencies and too much light go hand in hand. I'd dim the light about 10% to allow time to correct the deficiency.

I could see you had mg problems I was waiting thou as I wasn’t sure it was just that alone. Looks like you’ve had some good advise. All the best bud

Alway dilute the epsom in water imo.

Back the light off until recovery then crank that bitch back up

Diluted 2 tablespoons of Epson salt in 2 gallons of water this morning and gave them a drink.... I'll back the lights off as well. Hope that shot of magnesium helps..... They were doing great then bam.... Turned quick!

That's exactly how it happens. Your plants begin to stretch and boom, you begin to see the yellow zebra stripes.

Here's why ... LED lights seem to require the use of much more Mg and frequently Ca than HID and other forms of lighting. It's important to realize that Mg is the center most atom in the chlorophyll molecule so essentially that means its the foundation on which the chlorophyll molecule is built. If there's not enough Mg available, you see that tiger striping and eventually that leaf tissue dies. This is a light based reaction so dimming of the lights as well as supporting your plants with extra Mg is critical to its recovery.

It's also important to keep in mind that those leaves that show the tiger striping may never recover. Look at new growth to determine your progress. Mg also absorbs best (in soil based media) with a media pH of approximately 6.5 +/- .2

Edit: Above is the short answer ... a still short but more detailed answer can be found here:

If it were a simple Mg deficiency, you wouldn't see the bullshit on the leaf tips. It's triggered by the high light levels. But DO increase Mg.

Grandpa and Mosh are on the money in regards to the light especially being LED. Did you do the foliar?? lol .. it really is the difference between them recovering in ~2 days, or 1 week. Don't be scared of the so called "water droplet magnification" thing..it's largely been debunked.. especially since you can lower and dim your light...foliar feed it atleast twice per day,. during lights on, generally the stomata close at night.
