Hello Pushit,
As for PH I have a test kit with a small bottle of up and a small bottle of down. I hope I can manage the Ph level. After all I'm a first time beginner. I'm using a Hydrofarm jump start system (since I'm only starting with three in hopes of getting a girl). It has a full daylight spectrum 6400K lamp. When the flowers start I will switch to a warm spectrum lamp. I do, however, have a question. Do I switch the lamps as soon as I start 12/12 or wait until I see something resembling a flower? Thanks again. You've been a great help and it's better than traversing all the different logs to get one answer.
