Yellowish tips

[Rubby813]

Hi,
New to growing and a little concerned.
The tips of first leaves on 10 day old plant are showing a little yellow.
Should I be concerned?

Did you put fertilizer on it? Looks a little like nute burn to me.

I of course being a newbie grower wanting big healthy plants fertilized it once with pure blend pro gro 3-2-4. I Used a diluted concentration50% of recommended.
I guess the organic soil contains more than I think.
I flushed the plant. The yellowing seems to have stabilized, not getting worse.
How do you know when plant needs to eat?
As I said I'm very new to this.
Thanks for any suggestions.

Have you read thru the "How to Grow Marijuana" section yet? Thats the first thing I read thru when I started out, then Youtube is also a really good place to watch videos of how to grow (look for CO Finest). Me myself, I dont put anything on mine except a few drops of Rapid Start Rooting Enhancer by Gen Hydro in a gallon of water, when watering my seedlings at the beginning. I've made the mistake of using soil that has fertilizer in it as well and that burns.

Read this thread:

When should I fertilize my seedlings?
