Apollo 13 is Genius (a mystery seed found in a jack herer bud) x P75 (Princess cut cubed 75%). Everyone I've ever heard who's had Genius raves about it (one of subcool's faves...) as the super up motivational inspirational weed. Princess P75 was a predecessor to Cinderella 99. Cindy 99 = Princess cut P99 (99% genetics from the mother cut). Apollo 11 is Genius x Cindy 99 (have grown that previously and it was awwwwesome one of my favorites very clean up high).
What I've noticed about Apollo 13 so far from my early buds is that it is less inspirational than A11 and has a potent body buzz that I didn't really ever find in A11. Not sure if those characteristics will carry through, but pretty sure body buzz is only going to get more potent from here on out
A13 veg toppings quick dried/smoked from veg gave me a body buzz even.
I'm in super soil and have been supplementing with Pure Blend/Pro, but I've decided to back off those except for nitrogen boosts in flower or use in veg. For flower I'm only going to go water and/or foxfarm big bloom, but i just started using that. FF big bloom is <1 N-P-K in a flowering ratio (guano tea)
I topdressed #2 with super soil at around 3 weeks and I have a feeling that is why #2 has gotten so much bigger. I just topdressed #1 with super soil a few days ago. Going to be topdressing at 3 weeks (post stretch) going forward
