Led causing deficiencies

So i just got into using leds to grow and was wondering if anyone would know why a plant would be showing deficiencies under one light but not the other. Like can leds cause lockout based on spectrum ratio? Or cause a plant to eat more in one specific spot.

The plant in talking about is 90% under one light and is all green and then has a couple branches under another led that are showing deficiencies. Same deficiencies as the plant that is solely under the second led.

I know the lights are on in the pics, but the deficiencies are really apparent regardless. Any help would be appreciated.

What are the lights? Brands? Need pictures taken under natural light. One of them looks like potassium. More likely magnesium because LEDs are known to increase what is already a propensity toward mg deficiency. But, can't tell without seeing them under normal lighting.

It's probably just coincidental. Or, one light is brighter/more concentrated and you're getting bleaching from having it too close?

I have heard of such things happening in other posts. From what I see, I use led lights, the plants require more magnesium. Do you have brown spots on your lower leaves?

I have a ti smartlamp probloom 600 and a vipar c2x2. The vipar is the one causing issues. As you can see most of the plant is green, but there are 2 branches showing the same def under the vipar light.

Ya im wondering if its a distance thing because of the lenses. The lower leaves on the plant don't seem to be having the problem as much.

I still don't see anything in the photos. I'm wondering if it's bleaching. The Vipar is 5w bulbs with reflectors. I can't find specs on the TI. But, if it's 3w and/or uses a white backboard instead of reflector, you might have the Vipar too close. They might need different distances.

In those photos it looks like potassium to me. Someone else might give their opinion.

that nug looks tasty cheers for that .... im adding some cal mag to next feeding as i keep readin with led lights it creates lack of mag so will see what happens but my leaves looked similiar with that burnt blotchy look

The problem isnt what the deficiency is, more why its happening to parts of a plant that are under one light but not 90% of the plant.

Like 2 branches of a huge plant are the only part of the plant showing the deficiency. The rest of the plant is green like this

Not bleaching that I've ever seen, and I've seen it with HID and LED

Its not bleaching, its for sure deficiency but what do i do when 90% of a plant is green and healthy but 2 branches are showing this def?

Imo if it was a def. It would but the entire plant like all lower branches ir leaves all the tips etc etc. Since its just under that light i think it's bleaching or something is wrong with the spectrum that's causing iy.

It is a deficiency, but appears to be cause by a light that a couple branches of this plant are reaching over. I know what bleaching looks like, this is a pk issue and its only on the fan leaves also only under one light im running and not the other. Lol. Im assuming its deficiency due to lock out from spectrum of the lights, but it is 100% a deficiency not bleaching. The nugs look totally normal no discoloration or bleaching, just the fan leaves under one light.

Any chance it's a localized pest?

Nope lol. See where the plant reaches over under the led on the right? Thats the only place on the plant that shows the issue.
