Light burn or nute burn?

NeroBlackstone · Feb 4, 2021

I’m using growers choice 720s at 50% more than 36 inches above also
I’m feeding less than recommended so I’m not sure.
just surprise because I wanted to turn the lights brighter lol

Also one of them is curling at the top I’ll add it in there bongsmilie

also also anyone think they are too green?

Grab a grain of salt... Looks like classic nute burn to me.
As someone who burns my plants in every way possible, the light burn fucks up the whole leaf. Nute burn just the tips.

Very slight light burn IMO. I’d prefer to keep the lights turned down as long as possible. I dunno about you but electricity is expensive in California.

It's not nute burn the tips are not burnt

Not light burn. I'd sway towards a nutrient issue. Just give her a fresh water flush and continue on a lower dose for a week or so. I had the same issue not long ago when I tried a one part nutrient. Problem went away when I went back to a decent nutrient.

The leaves are kinda dark green. The only "burn" I see is at the very tips of the new leaves. Light burn can cause stress which manifests nute burn that wasn't apparent before.

I don't think you have a big problem (if any), but if you make adjustments, be careful and vigilant. You might be toed right up to max nutes.

(I put "burn" in quotes not to be a jerk, but to express that I don't think it's a big problem.)

Yeah, very minor nute burn from excess N, nothing to get concerned about. My plants look like this all the time, some strains are even just over sensitive too it. If it gets worse back off your N source.
