Preparing to Flower

1. Can I change my veg water to bloom water a few days before I change the light schedule to 12/12 to better the flowering stage?

2. Will changing it to bloom and taking clones from that plant after a few days of digestion better clones? (high pho)

3. I have a few that are over 24 inches in height, will a 400W HPS be enough light for these? I have 4 plants at the moment and they're Northern Lights x Big Bud. They're in a 2 X 4FT space. Ceiling is 8 feet tall. Anyone ever vegged a NL or BB plant this tall?

Thank you all, spread the word b!

1. no (you could, but it wouldn't help)

2. no (clones should be taken while the plant is in veg)

3. no (but I can say that they will end up 4-5 feet tall)
