    Raise the light.
    Going from CFLs to HPS is like going from indoors to full sunlight.
    Your plants roots were adequate for transpiration under low light.
    They are not up to the task in strong light and need to be "hardened off" gradually.
    Double the height above the crown, and vent the heat.
    When they have grown enough roots to handle the increased light, you can lower the HPS to it's minimum.
    If they were rootbound when you switched them you'll have to up-pot for good results.

    Thanks can't go any higher with the light but next time I'll try to wean them into the 600w hopefully these girls make it they are in 1/2 gl pots think that is big enough?

    I think I see the problem. :)
    Whether or not a 1/2 gallon pot is adequate depends on the size of the plants, yah?

    1/2 gallon pots are fine, for seedlings.
    But, they can not host enough roots for decent flowering.

    General rule. When your plants get wider than their container, or twice as tall as the pot is deep, check the root ball.
    If the "water roots" are circling, buy them larger shoes.
    Can't do your best if your feet hurt, yah?

    And, if you don't have any headroom, what will you do when they enter the 7th inning stretch?
    That 600W. light will fry the tops off. :(

    Aloha,

    I go from beer cups, to 4" square pots, to 7", then 10", (about 5 gallons), to flower.
    That gives me healthy 6' plants.
    For your 4' girls, I'd use 3 gallon final containers.


    I'm not parroting things I've read here.
    I don't know a whole lot. but what I do know is time tested.
    It's all personal experience from 45 years of growing.
    Some of these lessons were very costly.
    I had to unlearn a lot of idiotic "common knowledge" :D
    Hope I can save some new growers the same pain.

    Aloha,
    Weeze
