Maybe water a bit not sure

Just gave it a lot of water, i think i haven’t been watering it enough.
It’s on the window seal now and it’s very sunny.
Where should i put them during the night ?

what soil do you use?
make sure your PH is correct!

Hi thanks for responding,
i use Bio Diesel Max Air Coco Perlite 70-30 Mix.
and i’m watering it with a Ph of 6.5 water

have you sprouted other seeds in that soil?

maybe the soil has too much nutrients, for a seedling.

What should i do ?

i dont feel like i can give you advise on how to proceed…
i have never had that issue so i cant talk from experience…
maybe repot into lighter soil???

I just transferred the seedling in some tomato, vegetable and herb premium potting mix.
Gave it a water in its new soil so we’ll see if that helps other wise i have no idea what’s going on.

Welcome to the community ! My first thought The direct sun on your five day old Seedling might have been a little too much. When they’re that small they don’t need a lot of light to grow.

That looks like what happened to a couple seedlings I ran in coco that I did not wash or prepare. Did you wash the coco and buffer with calmag?

Thank you, how much sun or light should i be giving it each day?, i usually just leave it on the windowsill. Also where should i put it during the night ?

I use a small round 15 Watt fluorescent on seedling. Also I give 24 hours light for the first few weeks. Just about everybody has started a few seedlings in the windowsill sometime or another. I have never used Coco, @Eagles009 made a good point about washing it. Also the last picture let cup dry out before you water anymore.

Usually i’ll put my seedling in the sun then during the night i’ll have it under my 100w Pro grow ufo led light about 30cm away from the seedling, but i’m not too sure why those leaves in the middle went brown, it definitely could of been from too much direct sunlight, Anyway what do you think will happen from now on? will the seedling leaves recover and grow green ?

The brown leafs will not recover hopefully your new growth will come out nice pretty and green. Don’t give up on it you can nurse it back, it’ll be slow. Don’t overwater you might consider using a Dome and Mist the inside of the Dome a couple times a day to achieve higher humidity level.

May be using a soil that’s not correct for canibus. Ck out its formula vs a soil made for canibus. Plus at this age your plant has little to no root system yet to even take up water and neuts. The dome technique may be better for the plant.

My seedlings have done that before.
It happens when you get a tiny drop of water on top of the plant under the lights and it cooks the first primary leaves.
