So on Day 19 I topped #1 as it is a lot bigger and looked ready for it with 5 nodes developed and cut at the THIRD node.
At the start of the week I got the BIO Canna Rhizotonic so I gave each pot 3 litres @ 1ml per litre.
#2 Also had the Canna A&B added at 1ml per litre.
You can see the difference in #2 over night and within a couple of days it is looking a much healthier shade of green and seems to be developing a bit faster.
