    The reason is too much nutrient in the feeds, drop it slightly and no bloom at all (only for flower)...do you have an EC pen to measure feeds, at this stage you want roughly 0.3 to 0.4 above base (your water reading)

    Also a 600w light is too much for them at this age...they need gently bringing up to 600

    Cool thank you i will definitely drop the nutes! No bloom and i will lift my light farther away from them and see how it turns out!

    Hey guys new update!

    Bought an EC meter. So the plants look healthier much better and growing faster. My base EC is 78 with the nutes it is 451. I pooled my runoff in a bucket and got 720. My ph has been 5.8 to 6.0

    I halved the nutes as i said and have been feeding them more often and also feed them just plain ph water every other time Not to overfeed.

    The ones in one tent seem to be doing good but the 2 on the other have not been growing the same idk why.

    What do you think?

    Looks like they are getting settled and finding their legs. keep it up! Don't rush to add more feed until they visible lighten in color by a shade or two.

    Thank you!

    What do you think about my EC going in and the runoff? Im thinking maybe the runoff EC is too high
