Back to hand watering tomorrow. Worked before
That looks like early flower to me. The transition point. Appears to be little pom poms everywhere? Back right plant for sure.
Reckon they will keep growing as they flower
At this stage and current temperature, your humidity should be at 70%Do you recommend I drop the rh at this stage. I've been on around 60rh at 28°c. Last night my temps got down to around 17°
I just purchased a humidity temp data logger. I'll increase the humidity and see what they doAt this stage and current temperature, your humidity should be at 70% 
You should really look at the VPD, this is the combination of both temperature and humidity. Get to know this and and your plants will reward you for it 
I started using this chart. But after a while build a sensor that measures both variables and calculates VPD on the fly. Quite handy if you're a stoner like me...
Good plan! Stick to it and keep that runoff flowing.
I'm gonna measure the run off and ph. Just to get a closer look on what each plant is also using. I've also bought a temperature and humidity data logger so hopefully I can keep a better eye on what's going on and dial it in even more
Depends on what you mean by giving a haircut. Don't go @Vapo style on them this late in the grow. Go slow...start from the bottom and work your way up.probably hmgive the girls a hair cut tomorrow and remove anything out of the bottom. What do people recomend
