First Clone Question, (Pics)

So I picked up my new T5 lamp today, strictly for my clones. I'm using Botanicare Power Clone Liquid Concentrate Formula for my first batch. I mixed the solution as recommended on the bottle. I soaked my rockwool for 24 hours in 5.5 PH'd water. I cleaned my new pair of scissors and made my cuts at 45 degree angles and placed the cuttings in the rockwool. I trimmed the biggest leaves in half while leaving the little ones alone, like I saw in the youtube video about cloning.

My Question: When do I start feeding these clones? I'm assuming they are going to need some nutrients to start growing.

i just fed my clones for the first time, I jus gave them ph'd water for bout 3 weeks to let the roots grow first.

Really? Wow, how the hell do the roots grow and expand if they don't have any nutrients? Weird.

Ok, I soaked my cubes in the rooting formula instead of just dipping the roots in the formula! I was trying to use it as if it were a gel!

New Question: When the cubes start to dry out in a couple days, do I use the rooting formula to feed the clones.... or am I switching to my own nutes?

Rockwool cloning is a bit tricky to achieve. It has a near 100% success or failure rate. Most new growers do not start with it as a first clone attempt. I suggest you start with Jiffy peat plugs or potting soil in small cups as you first clone experiment.

But, if you are going forward with rock wool, I suggest you view some videos on YouTube. Type "rock wool cubes" or something similar in the search engine. There are many to view, that can give you help.
