Grandpa and Mosh are on the money in regards to the lightespecially 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.
Keep an eye on new growth it is likely more than just mag needed time will tellDiluted 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!
Hoping prob solved... New growth seems green... Have to get sprayer for folliar though for future.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.
Thank youThat'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:
Tips are Browning but new growth is green. ? Jacked light up as high as it will go and turned down as low as it can. After effects of mag deficiency?Keep an eye on new growth it is likely more than just mag needed time will tell
Tips are Browning but new growth green?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.
Tips are Browning now also but new growth green. Maybe top dress already with 444 and worm? That's be 2 weeks ahead of schedule though.... Could be heavy feeders? I'm def a newbie to insideKeep an eye on new growth it is likely more than just mag needed time will tell
If new growth looks good just cruise - don’t change anything for about a week after a few days you can start cranking the light back up - post up some more pics brown tips usually nute burn but let’s seeTips are Browning now also but new growth green.

The plant is taking Mg from other leaves and sending it to the growing points, so they show no symptoms.Tips are Browning but new growth green?
I'm running mine at less than 40% for plants in both early and late vegetation. I had it higher but saw symptoms of light stress. I'll separate the plants into different tents soon.I very rarely have my lights above 75% the lights just to intense
Just bumped my budding tent up to 80..... Now I'm worried. I'll def keep close eye!Yeah both calcium & mg I never had to use under hids, fluorescent & the like.
Caught me by surprise when I first started regrowing & switched to led as did the how easily it is to bleach aka light burn a plant under leds
I very rarely have my lights above 75% the lights just to intense
Epsom salts can up the ec and cause burn however it sounds like you’ve had some good advice
Good luck bud
Pics posted. Thank youIf new growth looks good just cruise - don’t change anything for about a week after a few days you can start cranking the light back up - post up some more pics brown tips usually nute burn but let’s see
I use an atomizer from a lens cleaning kit that was in the cupboard. Works great.Hoping prob solved... New growth seems green... Have to get sprayer for folliar though for future.
