Is this light damage from LEDs or over watering?

[TreeHunter]

2 out of my 6 seedlings have this and they are no closer or further away from the light source then the rest. The soil is still moist from watering 1.5 days ago. Using a 1500W 1' x 2' full range LED light panel which is hung two feet above.

Hard to tell from the info but from the looks of it you had water droplets left on the leaves which act like little magnifying glasses and can burn the leaves.

This is my setup.. first time obvi. Saving for a grow tent. I raised the light about 4 inches. Should I get a fan? Humidity is at 32% and temp fluctuates from 78-82 degrees. 17 hour light cycle.

 

[Beachwalker]

Yes, the fan blows between the light and the top of the plants, not directly on the plants

Not a led user so just a guess but since you have four of six showing the same issue I would guess that raising the light was a good move, often the manufacturers have a height recommendation chart for various stages of plant growth, perhaps check their website, good luck

I would also try to raise your humidity if possible, seedlings like around 75% RH and it can make more of a difference than you might think.

If it was me
Fix vpd + fix lighting issues

led’s temps 78-84f is what I would try to do , co2?

1.Use a different light in the beg if you can’t dim your led’s (raising it = stretch )because it’s obvious for that stage it’s over powered and your stressing the plants out and will do nothing but that. Over raising the light will just make them stretch ( if the light can’t be dimmed ) get a “ seedling/1st stage “ light meaning a cheap t8/t5 or a low level led and dimmable .

If you want the best light and be happy with your purchase and company, go with ethier of these companies, I would vouch with either of them 100%

example for the size of plants needs (if you disagree, directly to the makers website eh and tons of models <3)

2.Also I see your humidity in the picture states 32% for veg and following vpd , your way off and those plants need moisture or they can’t absorb .
