First plant from seed, Purple Thai bag seed...

First seed grow with a Purple Thai bag seed...when should I top it . Think I am only going to top twice and see genetics with a few big tall Colas, and see how much it likes to stretch. Looking more indica from the broad leafs. Beautiful node stacking, I'm thinking at the fourth node and three more after.

Looks healthy man good job!

Little update, topped once still staying squat

She stalled for a few days after topping but is starting to shoot two mains now. Hasn’t seemed to effect undergrowth and stem. Main is thick as a pencil , Mopar neon green with purple racing stripes. Hand size leafs already, leaning toward Indica. Backed it off light to stretch a bit. The stems on the leafs are V shaped and have a prominent valley running down to the stalk.
