Day 45 - They are going through the stretch and both #1 and #2 are flowering well. #3 is behind but has been a week behind since the beginning. She is also fuller with larger leaves and a shorter stature. I'm not sure if it is a different phenotype or what is going on. I gave the ladies straight water today but next time I will add some flowering nutrients.
Day 47 - #3 is starting to flower. She still looks quite different from the other 2.
Day 49 - #3 is still growing taller but I think the other 2 have stalled. They won't be very big but hopefully they will produce a decent cola. No trimming needed as they have very few leaves and they are well spaced out.
@Chlorophyll_Junkie,
I use 1 Phlizon 600w light and 1 Aponuo 1000w light in this tent. Both are cheap LED lights from Amazon. So far, I have been impressed with how well they work and how the plants seem to like them despite not being top of the line lights.
