A lil yellow in LCs mix?

I have a clone thats rooted and been growing great for a few days now. Actually its still growing fast. The prob i have is that it has a little bit of yellowing on the leaves (pic included). Im growing in LC's soiless mix #1. I added the bone meal, blood meal, kelp meal, lime, molasses, and some mycogrow along with the main ingredients. Peat moss, mushroom compost, and perlite and let cook for maybe a month or so. It doesnt seem to b a vry big prob right now but i want to take care of it before it gets worse. If it is a prob at all. I posted this here in the organics cause id figure u guys would be more familiar with the medium i have prepared. Its under a 250w MH light and the temps in that room hang around 80 or so degrees. Other clones in the same room and medium are not showing signs of this yet. Any help or advise would be appreciated. Maybe i missed something i need to add to the mix. IDK. Oh and the ph of the soil is about 6.5.

Oh and also this little seedling is gettin a little yellow around the edges. I know its kinda hard to see but my cellphone camera is all i had

I also run LC's#1 and ran into the same thing on 1 plant.

1 application of epsom salts to that plant and it's fixed.

It's like the lime wasn't mixed well enough, or the plant hadn't reached it yet or ...???????

After the 1 application, the plant is growing as normal once the roots got farther into the mix I guess?

Ok thx alot. So is it 1tbls per 1 gallon of water?

That should do it, or perhaps just a touch more, I use more like 1tsp/qt.
