    One seed has popped and been put in a rockwool cube with no nutes at all. I think by the time she surfaces I will go in with 0.2 made up with formulex and see how I get on.

    I've never seen a seedling with roots so small. Usually I'd expect the tap root to have broken through bottom of cube and roots poking out the side after a week.

    I can only assume the feed was too strong. The humidity was on the lower side, 50-60% but nothing drastic. The temps were good too, hovering around 25C.

    Hopefully I'll see some signs of life tomorrow and start all over again

    Cheers

    Quite often the seedling will surface a few days before you see the taproot, not always, but it doesn't mean it's fucked. Just got to let it do its thing. Other times you'll see a huge taproot days before the seedling surfaces. Pretty unpredictable tbh

    All I use for 1st week or so is rhitzotonic then a week feed of 0.4-0.8.. But this is 1st time in many many moons I've gone from seed much prefer cuttings but same strength feeds apply.

    Edit just to add I don't worry about humidity I'll be taking cuts soon and you will see I don't spray or cover them !!
