Light burn or deficiency??

Have a few weeks left in flowering ,
Just got a new quantum board light.
Is this light burn or a deficiency???

lights turned down to 50 percent to start .
didn’t think that would burn them
#leafissue #lightburn

Also leaves seem a bit dryer than usual

All things being equal, I'd say it's a deficiency.

However, what type of light were you using before switching to the Quantum? How far is the Quantum from your plants?

I'd also check your plants for pests.

That's a nutrient issue...which is hard to diagnose...light burn with LEDs looks diff in my experience...bud tips will be bleached white n leaves will b bleached n yellowish lookin n have a tie dyed look

Your leaves look well fed...you even have some burnt tips which I desire bc it lets me know she's eaten good...I'd lean more towards on over feeding of something than an under feeding of something...I would water em with straight water for a few waterings

I had a mars 2 700watt. Burple

quantum board is about 30 in away
And dimmed down to 50 present.
Figured I’d start low work up

Yeah I've definitely had light burn with a blurple... I have an Advanced LED I still use occasionally...I push it close as I can to get the most I can out of it...so the 1st sign you'll see from blurple being too close/intense is bleached white bud tips...leaves will b affected next n not even so much really...just some weird tie dyed look n maybe some warping of its shape but the most noticeable thing will be the bleach white bud tips especially when the light is on it really stands out

Affected leaves will not b crispy or dry feeling they still will feel like a healthy leaf...if they are healthy...

I didn’t notice anything until a couple days after hooking up the quantum board.
unless it wasn’t as noticeable under the old light. being the burple colour

This plant I just harvested...if you can zoom in this was the only bud that started to show signs of led being too close...part of the bud tip started turning white...so I knew to keep light at exactly the distance...I've had ones where an entire top bud was bleached white...its actually cool af...I just let it go bc to b honest the only off thing was the bleaching white...resin still packed on tremendously which on the bleach white bud made it look alien af...its really not that bad of a thing as long as ur plants healthy n thriving

Oh...well the light switch could have something to do with it...idk...that would make me suspicious too if it happened right after I changed something

Ok
I don’t see my tips going white . Ill just keep an eye on it.
Thanks
