Noobs Hydro 1st Grow

After a semi successful grow in soil last year, but with problems with thrips and spider mite I wanted to try a hydro grow. I had a read up and this is my first attempt. I chose to grow a strain Ive not smoked before Candy Kush. Out of the 3 seeds I had unfortunately one failed to Germinate however the remaining 2 sprouted quickly. I also planted a Northern Auto seed I had from last year but for this diary ill concentrate on the Candy Kush.
