Deficiency issue: trial run for my first grow, outdoor coco & perlite

[robth420]

Hey there!

I'm running a couple trial plants to try and get any of the initial issues that I may have starting my grow this year out of the way (hopefully)

The issue started out as yellowing of the smaller leaves and while one seems to have turn back green, the other has started to turn brown on the tip. I bumped up the nitrogen in my solution but wonder if theres possible a nutrient lockout or it could have something to do with not washing the coco.

Below I will list the details of my current grow state including pictures. I believe it may be a nitrogen deficiency, however I started this trial before
understanding the importance of flushing coco and adding calmag so that could potentially be an issue as well.

Any and all suggestions are greatly appreciated

Thanks

It looks like it's the cotyledons (first pair of leaves) that you are asking about. I wouldn't worry about them, just the leaves that grew later.

It could be you didn't charge the coco. They are young, charge some coco and transplant, be careful with the young roots.
