Seedlings has white hairs on day 4?

[hairyjared007]

Hello everyone I'm new to the forum. I hope someone has experience with this.
I'm growing indoor with coco. Out of my dozens of seedlings, 4 blue dream seedlings have white hairs on the tips of the leaves. They sprouted 4 days ago. Ive had them under a led/hps mix thats low par for 19on/5off.
These white looking hairs are coming from the leaves tips.
Here is a pic:

Thank you, glad to be at a new forum. I'm pretty lost as its coming from what looks like the leaf itsself...like the skeleton of the leaf lines up with it from underneath. If you can understand what Im trying to say.

It's a deformity of the leaf tips. Did you flush your coco or precharge it?

looks like the early stage of hot medium mutational burn

I used a new bag of high quality washed coco, and used Zeus Juice by nectar for the gods used as a germination aid, softening the seed coat and providing nutrients for the first stages of life.

Too hot of nutes then. I've done it, shit happens.

Just keep it watered.

Yeah, I typically don't even feed nutes for the first week. Sometimes longer.

IMO a seedling needs nothing but water until the cotyledon start to fade/curl.

Stop feeding, it might recover.

That whole cotyledons fading and stuff... Never got it. Mine are usually green weeks into veg and I usually trim them off when I pop the bottom.

That said, I'm not disagreeing with you about using them as a gauge. Just saying.

You're going to get a pound from that plant!

Not a problem.
Some seedlings can handle nutes early, some can't (like the OP's pic)
This wee one was just fed (1/4 strength) for the first time.

 

[Logan Burke]

I've had cotyleons turn yellow as early as week 2 of veg, and I've had them remain green for nearly an entire grow...never really did understand why.

Better hurry and get a scrog up
