My plant: Week 2-3

Hey there. This is my plant at either week 2 or 3, I can't quite remember. I want to say 3. Anyways, yep that's it. I was a little worried because the new leaves have a yellow tinge to them. I'm also wondering what the blurry stuff is in the middle. It could just be the picture.

I was also wondering when I should start nuting. And if so, how much? I've read that you should do 1/4 the recommended dose. My recommended dose is 1/4 a tsp, so should I do 1/4 a 1/4 teaspoon?

I was also wondering when I should start to LST.

Also, how much should I water? I've been watering enough to get the top soil wet, and the last time I watered, I gave it probably 3-5 cups of water.

thats a big ass picture man haha

Holy massive pic Batman!

When you start feeding depends on your soil. we need more info. my recommendation is mix one full strength batch of nutes and then dilute from there. if your nutes call for a tsp per gallon and you want a quarter strenght dont try measuring out a 1/4 tsp. put the full tsp in 4 gallons of water.

let it get at least 6-8 inches tall before lst. But, if you want to grow it really bushy and tall, you could wait till it gets to be 12-18 inches before starting, although starting at 6-8 won't hurt.

Now for the color of the leaves: did you use a potting soil with nutes already in it? If so, you don't need to be adding nutes now. Wait a few weeks for that. But if you did use something like miracle grow soil and then you added nutes, you need to flush the soil 2-3 times with water to get rid of the extra nutes.
