Led Burn or nutrients?

[Trout2012]

So this is my first use of LEDs it doesn't feel too hot but maybe I'm wrong. I'm just freaking now!! Just put some ph adjusted plain water in just in case. They are just starting the swell dont want problems now!! Anyone experience LED burn?

Looks more like a heat issue than light burn to me though it could be nutrient related if you fed real heavy. LED bleaching looks just like you bleached the fan leaves; the veins turn almost white and the leaves turn a very pale green. LED burn usually affects the topmost growth first. Probably couldn't hurt to pull the lights up a little higher if you can. If it's from too much N just back off and give straight water for awhile. What are your daily temps like?

I have been fighting temps a bit, but are like 80 to 83 now. My light was a little low this bud was pulled to the side the top was actually above the light. My water reservoir was extremely low also, but couldn't have been more than a few hours. It's the totally brow in little time that's got me stumped. Maybe a combanation of things? My nutes are just ionic bloom and PK boost! I wouldn't think my N got to high but maybe. Now that you say heat though looking at my pics the green leaves do seem a bit droopy!! Thanks for the reply sometimes an extra set of eyes helps a lot Thanks!!

How high is the light?

 

[Trout2012]

From the actual burned spot about 10 inches. The rest of the bud is above that and above the light. I already feel like a puppet master I got strings tacked everywhere. The light just doesn't feel real hot. I know if it was a hps I would have no choice but to bend it supper bad or supper crop, I just figured the LED would be ok.

Nutrient burn.

That's why it's working from the bottom up. If it were light burn, it would work from the top down.

Nutrients all the way. Look at the clawing and leaves cupping down.

Raise your light. Read the instructions that came with it. Suggest raising to 22” at least. Or bending the hell out of stems. I supercrop aggressively. Even through the first month of flower.
