First Time Cloning

I am cloning for the first time. I have grown successfully two times, plus these mothers, but this is the first trying cloning.
After cutting the lil guys, I dipped into Olivia's Cloning Gel, and inserted the stems into Delta Rockwall. I use General Hydroponics nutrients but don't know when to start using the nutrients. Any tips?

Dont use the any nutes until you have roots developed. Foliar feed with properly PH'd water.

Its always best to start off slow and work your way up, ecspecially with GH. Have you experienced any nute burn in the past with GH?

Are you cloning male plants? 'little guys'?

No, they are all females. I have never experienced nute burn with GH- have you? Typically, how long does it go until nutrients should start being used? How are you doing the Foliar feed?

Cloning in rockwool is hard without any nutes. what kind of water are you using? i tried using RO water in rockwool and they just kept going bad, started putting cal-mag at 200 ppm in the water and now i have roots. It might work better if you use some good well water, but ro water is too clean imo
