First grow Auto Moby Dick XXL- outdoors

Hello everyone! Today I've got some pictures from my plants, at the moment I'm far away from them, but my mother is doing her best to take care of my babies. As the last update I see like there are some problems on the plants, I don't know what could be, because i'm a little far away from home.... :( For example on the sister 2 I see that the green it's getting pale, like 2 or 3 days ago she did a defoliation but it seems that it needs a hard defoliation, what do you think ? I think that these babies need to use the energy on the flower and not anymore on the leafs, this friday i will return home and I will apply the corrections that you give me, but please, tell me anything. This is my first ever grow and I don't know so much what I need to do. Another important thing, I was thinking on start flushing them on wednesday (as the babies have like 2 more weeks of life or that is what i think) If I start it on wednesday (Jan 8th) they will get like 14 days of only water, but if you tell me to add any kind of nutes i think that i can start the flush the saturday. Please, help me, I would like to get the best quality buds on my grow, i know that i've commited a lot of mistakes, but that's new knowledge that i know already for my next grows!! Thanks so much for the attention. Have nice grows and good harvest everyone to is following my diary. Ps: They aren't the best pictures of the world, but my mom isn't a professional, me neither but....
