    Anyone know whats up with these seedlings. In a mix of soil, compost/ewc, perlite, vermiculite. Very small for 2 weeks old and now they are curling down and turning colors. The white is just diatomaceous earth.

    Hey bro!! :mrgreen:

    Yeah I reckon.
    It's your description. They should be a lot bigger at 2 weeks old.
    I did the same thing, one time with some outdoor soil. Instead of buying seedling mix.
    My mix was way too hot. Sprouts never got past their first node.
    If you've used the same lights before. I think it's a hot mix for sure.

    I reckon just plain seedling mix.
    Leave the stronger stuff for later, I say.

    Back them up a bit. They should be fine at that distance but it may be a bit much.

    I just don't see your mix being that hot.

    Is there an npk analysis, anywhere on the bag

    How do you prepare your substrates? Perlite, coir, and peat moss?
    Did you give each, a really thorough rinse before using?
    Did you add any lime or gypsum, to buffer it all?

    What type of CFL? anything up to about 25W should be fine even at 1 inch.
    It literally as to physically touch a leaf to hurt it.

    Yeah man. I'd go something milder, TBH.
    Just an ordinary seedling mix, from the hardware would be more than ample.
    I don't mind those jiffy pellets either. But not practical for your situation right now.

    Cool.
    Sounds good then.
    Soooo what's the problem? :bigjoint:

    You're right man. This is a good one.
    Maybe transplant isn't necessary.

    What's the ph, of the mix you used?
    Did you check it before you potted?
    Is there any extra lying around, you can test?
