What could this issue be?

Brown spots on leaves. On the tips of some. Growing in 3/4 black kow cow manure and 1/4 organic promix.

Also when I look at the underside of one of the leaves it looks like the silhouette of a worm shape if that makes sense

edit: sorry I know some of the pictures are hard to see.

probably soil is a little hot, easy on watering, roots need airflow/oxygen, holes in bottom and sides i prefer.
lights a little close?
it should work itself out, don’t have to do much yet, just check in on it daily.
post more photos if it gets worse.

Hi!Cow manure retains moisture,also it could be hot for seedlings.How old is it?I'm not familiar with "organic promix"but sounds like it has enough food for small plants if you use it clean.And you could add the cow manure later,when they are bigger.You can make the opposite:3/4 promix and 1/4 cow manure ,so much is not needed.Now you could leave them dry more before watering.

I agree with the 75% Promix and 25% manure, although make sure it is composted first as raw manure can burn the shit out of your plants. I grow in Promix using the 80-20% ratio, but 75-25 would also be great. I think the medium might be a little hot for starting off, but once the roots grow in and the plant grows a little bigger, it will grow so fast the leaves won't have a chance to turn brown!
If the Promix that you are using has nutrients in it (I use the Promix HP or HP which comes without nutrients), I would go easy on the manure as you are adding nutes to nutes. As long as the plant is happy, you are fine. The slight tip browning isn't a worry unless it starts getting worse.

That’s what I was thinking too that it might be a little too much since the plants so young but she’s looking happy with it so far. I couldn’t for the life of me find any normal potting soil with no additives!

Thanks buddy, I’ll keep an eye on her!

Great idea for this mix ratio! ^ plus you might want to consider adding perlite so it drains better

My neighbor was using this in his garden yesterday as a top dressing, it's strong and looks easy to overwater? Good luck!
