My Polar Gelatos are about 2 weeks @ 12/12. The left plant seems hungrier than the one next to it. It's drinking the same and has had the same amendments.
For the most part they are growing well.
Mac is about 2 weeks @ 12/12 and doing okay. I'm hitting the canopy with some heavy light to help minimize the stretch. The light is approximately 12" away at full power. Lots of air flow going with a 6" fan down low and high. Humidity's been around 60% and temp. has been ranging between 80 and 70F.
I'm losing a few leaves down low so I'm not trimming her up yet. I think it'll be beneficial to leave lowers to help feed her during stretch.
I will thin it out after stretch or when I can find time, I've been pretty busy lately.
