could this yellowing of the plant be light burn

[biggerbud420]

i got 7 plants in this tent i got 2 plants 1 acalpulco gold and 1 gdp this is happening too it's really bad on the aculpoca gold . i was told it was light burn but could light burn only affect 1 or 2 plants under the same light ? i have a spider farmer sf4000

Are you able to post a close up of the plants you believe have been burnt? It's possible its due to light burn but all I see is an abundance of buds in your picture.

It could very well be some minor light burn. Your plants over-all look very healthy so I don't believe you've got too much to be concerned about. It's impossible to grow a plant like cannabis and have every leaf on the plant be perfectly green. Older growth fans eventually fade and drop off the plant. Plants are looking plenty frosty ...

Thats what I hate about leds. You don't see the damage until its too late. If I remember correctly, you had it really close and raise it a few days ago.

i know over all it's good but it is driving me crazy as to what it is lol

and if it is light burn why is it only affecting those 2 plants can u have mutilpe plants in the same tent and only 1 suffer from light stress ?

I see zero light burn. I do see differences in strains.

What you're seeing is likely the damage that was done prior to raising your lights. That won't heal, but the damage still looks relatively minor.

Quantum boards are very focused lighting and are known for producing hot spots. When I use my quantum boards, I set the distance at the high end of recommended and then let the plant grow into the light. Buds that get too close for comfort will look like they're trying to get away from it.

If the tissue is actually damaged, it will show little to no trichome development there. But I have not seen anything that I'd be overly concerned about. Over-all, great job!

It could be the beginning of "fall colors." Your plant is maturing.

what is it in? dirt i mean?

If you have a way to dim the light slightly, then do that. But color varigation is normal. Especially between strains.
Do you think and indica and a sativa should look just alike? Structure, function and color all vary constantly.
