First time indoors

[xasiklis13]

Hi guys, first time indoors(have grown 3 times outdoors) and i have a couple of questions. Just bought a budbox 1.2x1.2x2.0 with a sylvania 600w hps and a fan with carbon air filter. I am also waiting 10 Barney's LSD feminised seeds. Barney's farm says flowering time 60-65 days, so when will i have to turn the lights 12/12??? And after germination and transplant when should i start using fertilizers(i have the full ionic pack)??
Thank you for your time
cheers, xasiklaros
