Sprout with nute burn?

[elcoloan]

Hello friends
I have this sprouted Auto WWxBB from Female Seeds. I put her seed in warm water on jan 22, and passed it into coco+perlite 4 hours after that. Today cotyledons opened and i noticed that the tip of one of the serrated leaves is brown... could this be nute burn? The coco i used has a runoff of 0.2 EC, haventwatered it once since i put the seed in it.

2 questions,
Was the coco conditioned prior to planting?
What is the ph of your run off so far?

Yes, it was buffered with CaMg at 1.2 EC and then used water at 0.2 EC and pH of 6.0 until runoff matched Ec of input water.

I wouldn't get to worried yet. I'm not familiar with your genetics. I've had some in the past that start a little shaky. I start two seedlings generally in each final grow bag. After two weeks I cull the weaker plant. This can slightly scue selection towards fiber producing plants,but it quickly gets rid of weak genetics. Good note taking will help you determine if it's genetics or a soil imbalance that can be fixed easily. *( I only grow organic)* so my soil remains very consistent. Yes organic is a very broad word. To me organic is strong microbial life and happy worms in my soil. You might want to germinate another seed in soil that is untreated with any added nutrients.
A healthy seedling will quickly make up ground versus a weaker seedling.
Peace brother

Ya see, that kind of quality answer is what we need here on the site, as many others contribute.

I especially like what you said about the better seedlings will pierce ground as stronger genetics.
There is a lot of truth to that.

Cleaning up the gene pool is something we (collectively) can work on for the future.
Unless of course the grow is left to nature to decide (RE: Darwin??)..

Thanks all... definitely just over-worrying... this is how she looked this morning:
