9/10 - Watered today, with the 3g pot getting 1.75L and the 5g pot getting 2L of water.
9/11 - The plant in the 3g pot is currently about 13" tall, and the 5g pot is 15" tall.
I'm currently growing this too and some of my fan leaves are doing the same thing, maybe it's just a genetics thing after all or they just love there nutes! Glad to see I'm not the only one with this problem though.
