Oh- one thing I forgot to mention- the plant has always shown red petioles, typically a sign of S def, but in this case I am feeding a VERY high S fertilizer (cornucopia bloom) and the only plant still red is my MTFs. I think it's just the strain.

Node spacing- I have not grown this plant outdoors and don't know how much stretchier it would get under natural sunlight.

Yup, the seedlings showed some purple hues when they were very young too.
