What's wrong with my baby?

Take a look @ the pics. The older leaves are becoming a bit yellow in between the veins, and I see some folding down. Any idea what the problem might be? It's definitely not nutrient burn because I barely added any nutes at all. . .

possibly a little low on nitrogen. How much is in the nutes you are using?

I have an all purpose indoor Miracle Grow NPK 8-7-6.

Then there's definitely no nutrient deficiency right now..

A lot of plants have little issues and struggles in pre-fertilized soils. The vast majority of the time, they pull thru on their own, and it's best to just keep them lighted and watered -- don't start bopping around trying to "fix them". I've gone thru this and learned the hard way.

Your plants look good to me - I would just stand down for now.

yea i'll just leave 'em. this my very first plant so i'm always worrying. it's Nirvana's Papaya (fem.). i can already smell the fruit!

I know how it goes. I watched every single leaf come out in my first grow...
