Take some photos under natural or incandescent. Cant see shit under those LEDs
Since you are guessing burn what are you feeding them?

General Hydro. My ppm is 180, I think it's a little too high for them this young.

When a plant is just a seedling I tend to be more concerned with how it is doing. With so few leaves it can't afford to start dropping them. I've had some small plants begin curling up and dying from the bottom up until I changed the soil. What's causing the leaves to change I don't know. From what I can see, the leaves aren't turning yellow and dying so you should be able to figure it out before it takes a dive. The sooner the plant gets what it likes it should begin to thrive again, unles the get stunted...

Yeah I usually start around 50 ppm and just start increasing the nutes. Started too high I think.

I start nearly all my plants at 150-200ppm without ill effects. This is 500scale which equatea to .3-.4 EC
Got plants at that size at 300ppm with 80ppm tap. So 220ppm of nutrients.

Herr are some without the LEDs on. They still looking bad and I am using Aerogrow Nutrients, forgot to mention.

First off how long have they been under the LEDs? It looks like Ph fluctuations or poor oxygen by the look of the droopy leaves?

Hey Buzz Buzzilla thanks for the response. I have had them under the LEDs for about 3 to 4 weeks maybe. I haven't ever had this problem. Let me ask you, should my tent be sucked in like a vacuum? The oxygen suggestion sounds about right. Here is
a pic.

I have had some PH Fluctuations as well. Had to get some calibration fluid for my meter and they spend some days in the incorrect PH. I am still not too sure if the meter is accurate, I have read some reviews on it(PHT-026 5 in 1) and they too say the PH was iffy even after calibration.

Yes negative air pressure is good for odor control...but I'm referring to the oxygen at the root zone...you said hydro, is it a flood drain system? Recirculating? Raft with a bubbler?

Bin with an airstone and pump (Aeroponic). Here's a pic.

Well not too much water then! Over watering and under water have the same look...so maybe not being sprayed often enough or the misters missing the roots? No experience with aeroponics, just trying to help problem through the plant....i have had similar spotting problems with changing lights and using lights with uv cause radiation burn.

I wonder if my lights are too close, this is my first time working with LEDs.

I had a similiar problem, the problem is it could be a lot of things. My problem personally was that my plant was hungry as shit because I had the ppm at like 80ppm. Mine was even worse looking. Raise that shit up to 200-300ppm and see how it reacts. Use Hydroguard too, that stuff is fantastic. Everyone kept telling me it was under or over watering but it was just hungry, so try to feed them a good bit before wasting money on more airstones and shit like I did.
I'm talking NaCl EC/PPM conversion btw.
