Third time's a charm

Might win an award for the smallest, most underdeveloped plant ever....don't get me wrong I couldn't keep a huge bush, but this is ridiculous. Im so sure its the smart pots doing their job, just a bit too well with air trimming of the roots. I was very tempted to abandon this one and start again with some proper pots, but i feel like I've gone too far and as she's started to flower I might as well waste another 8 weeks.
