White Widow, with pics Must see. in flowering. need a suggestion

hey guys, below are my two babies, i used the FIM and Low stress training method... Strangely enough, i Fucked up the FIM haha... never happend before, i cut it too high being paranoid ....

my concern though is another.

as you can see in the pics below, the one on the left has a nice dark green shade to it, whereas the one on the right is much lighter... they are fed through this water-pump system i created so they are recieving the same amount of nutrients all the time...

can someone suggest what might be the answer to this wierd situation?

cheers

have you cheked your plumming?

everything works perfectly, i check it every morning
