I'm not sure I totally get the whole picture here... but why did you have to sex the clone if you knew it came from a strong female plant?
And there is a difference between guessing something is fine... and knowing something is fine :rasta: A full point off in pH can really funk things up. A pH of "probably 6" does not equal 6.9 :hippy:

But yeah... so why did you sex the clone?

Edit: I just looked at your pictures again. I can't seem to even see a single speck of perlite in your soil mix. Did it run away? :jointsmile: If that's tin foil... it's probably doing more harm than good. Flat white paint seems to be the most user friendly. Is that a tray under your pot? You don't want any drainage water hanging around. Soil looks like it's very soggy too. How often do you water and how good is the container drainage? The leaves look a bit droopy, which could be overwatering. What's your exhaust like? Are you guessing the temps or do you have a thermometer in there?

And WTF is that first picture of? I think I kinda see an arm? :wtf:
