Identifying Seedling Burn

Hey ILGM, new to posting, but been lurking for a while. So, I’ve started my first indoor grow, and ran into my first issue with this possible light burn.

What I’ve done: Raised my lights to 23-25in above them, both side seedlings receiving 16-18 DLI, with the littlest one receiving 14 DLI on an 18/6, being little over 1 week old. After all that, is there anything else to be mentioned/fixed? Let me know, thanks! :slight_smile:
Also, will the little one survive?

Welcome to forum.
When you water keep water away from main stem.
Water every three days or so…
What soil are you growing in?
Your tiny plant, I would put clear plastic cup over the top for humidity and water around cup…

Hey, thank you for responding! I was thinking the same and had put one back on before lights out. It’s definitely weak, and humidity with my temps averaging 80F during peak. I’ve watered as such mentioned too, most likely due for another one. However, the clumped parts are a mistaken top dress with Grow Recharge, also using Grow Dots (2 Light feed, 1 with medium feed) + Mother Earth in 3 gal pots. Either way, I’ve broken up slightly the soul and chosen to list around the plant, including watering like mentioned. Next time I’ll use recharge through watering.
Appreciate all the help:)

Welcome to the forum. They look normal. New growth is vibrant. Raising the lights is good as a little stretch in veg this young is ok. Auto flower so we want a strong veg with taller plant. Just watch for tall and lanky. If that starts lower lights and givem more juice.The first leaves get sucked dry and die off quick. You will see an exponential growth spurt within a week from here or so. Keep on sailing.

Those seedlings look to be struggling to take up water because the nutrient charge in your soil is too strong. They’re nutrient burned.

Soil looks too wet for seedlings. As said above id dome them and mist the dome.

Good morning:) @Cap_Ron I definitely see that being a problem too, anny ideas on a solution? Maybe I could take some of the recharge off and just toss it, or dissolve it into water for next time?
@Audiofreak I’ve applied the dome beginning this next light cycle too.

I leave dome on till the leaves touch the sides of the dome. At this point they have few roots to take water directly except thier leaves.


I pull the dome at this point

@Homayoun, what kind of soil is it? If it’s something that has any kind of a charge of it’s own, like Ocean Forest or anything similar, then you should try to remove anything that you’ve added on top if you can scrape it off. Seedlings need very little in the way of nutrients, and even what’s in Ocean Forest right out of the bag can be too strong for them sometimes.
Just a note, if what you had was light burn, you would have seen the seedlings leaning over or even falling all the way down to try and escape the excessive light.
Also, seedlings do a lot better in much smaller containers. You can have much better success starting in solo cups and then transplanting into bigger pots down the road.

Looks to me like the 2 leaves touched the soil maybe.

Very good mention, I didn’t know plants would react that way haha. I’ve done some of that for my little one, trying not to disrupt her too much, pray this day is all okay then I may change more things, currently at work!:slight_smile: but, the soil is pretty good. I’ve added in 1/4th perlite to the mix too, also mykos is in there, so recharge is definitely not needed right now .:sweat_smile:

Thanks again, appreciate you all:)

Also forgot to mention, the soil is a 12-6-9 mix, it’s Mother Earth Potting Soil, blue bag, also just wanted to have my autos in their final home, I understand watering and soil maintenance is easier with 16oz cups, just trying to see if I can safely skip steps, still learning of course.
