Update, day 26ish - both been topped at the 3rd node and will be trained outwards whilst trying to maintain a flat canopy. I will not be training the secondary branches in a main-line style as I believe this is why I got thinner buds last grow. I will just try and form 8-12 nice fat arms by the end. We'll see how that goes. I am using metal hooks for the first 2 nodes each side of training before starting to use the wire.
Today I defoliated 1 leaf on each side of each plant, it kept covering the tops trying to get light. I can see an immediate response, that was a good move. I'm going to go a bit easier on the defoliation this time around.
All in all pretty happy so far. The BD x T is really liking her space at the minute.
Autopot system has been on and off - I think there was an issue with one of the valves and it kept the CBD a bit waterlogged - so she's a couple of days growth behind the BDxT now. Going to keep the system off for another 2 days or so and get those roots a bit more expansive. Then I'll switch it on.
