Are you using bio buzz soil too? Have you mixed in perlite? What type of pot are you useing? I'm in bio bizz light atm didn't start with nutes till week 4/5 I think. They defiantly don't need nutes now. If your in the right sized pot then water until you get run off. And no dude use em or lose em lol.
When to add nutes depends on soil. As I say the little seedling don't need anything but water yet. Just check your soil when you can. Also make sure you get perlite and add in generously to the soil when you transplant to bigger pots. Water them till you get a bit of run off coming out the bottom. I can't actually help with the schedule cause I got bio fizz soil with fox farm nutes. After this grow I'm gonna go all bio bizz I think. It's much easier for me to get. But starting at 1/4 strength is a good starting point, but as I say not yet. Good luck
