you will get different answers for this question. Some guys keep them green all the way through. The reason fan leaves yellow and die off is lack off nutes (N). I like letting my plant yellow off. This way the nutes locked in the plant are used to produce more bud. I just think timing is...
One thing I didnt realize at first is the r/o machine had to have the pressure tank hooked to it or the float in my main res wouldn't shut off the water.

Looks a little light on top maybe feed her more or what about co2/fresh air for her? I attached a link to plant guide maybe it will help.
This seems to work for me but please read the warnings, These things put off gas that is not really good to be around for extended periods of time.

Are you sure about this?? Because I would think given the time all of them would turn amber. Some obv take longer than others due to lineage and stress factors but all fruit ripens in time.
they will root lots faster if you shut the pump off sometimes.
If you run it constantly then one of two things might happen
1. Plant lives with no roots
2. Plant develops stem rot.
Dont drown your babies! Water tillwet then turn pump off till dry. The timing just depends on exact setup.
