  1. Hi,
    I am a 1st time hydro grower. I have a few questions I could not find anywhere. Help would be greatly appreciated please ...

    I am growing purple kush,

    1. How much taller will my girls get once I switch them to flower 12/12 hr?
    Twice as tall as they are at end of veg?

    2. My ppm was way to low when I started, got some plants with yellow fan leafs on bottom. I have raised the ppm to about 925 and they greened up except for the bottome leafs.
    Should I cut the yellow bottom leafs of that are not receiving more than 50% light?
    Is my ppm correct now about 925 and keep going up as I flower?
    How do I tell if ppm is to high? Some leafs have yellow tips, is that nutri. burn or still from not enough nutri earlier?

    3. Should I turn off my fan that cools my plants while the light is off or does it matter?
    I have them in a small closet that I have to open to blow the fan in cause of space. Its dark, but when i flower since i will be home to open and fan when light comes on, should i just close closet with no fan so its complete pitch black?

    Thanks for all the help guys ... Ive been searching in the growers bible and everywhere online for these 3 questions. I really appreciate it.
