RQS Shogun and Green Gelato

Well i'm facing a big problem !! Next week on Thursday i'm leaving for 6 days so the plants need to be ready to harvest before i leave. So last week i put the plants on 10/14 hour light shedule to speed up the flowering time. I was looking for a solution how i could have the plants survive for 6 days without me at home but 6 days is impossible not to give them water so i think they will die when i get home. So i think i will harvest them a bit to soon just to be sure i will still have weed. Such a shame i can't let them grow to full potential :-( On the Photo's you see the effect of the aphids attack some of the leaves were a lot of aphids were are going yellow. I sprayed the plats 2 times with biological spray to kill them but it does not seem i got all of them. Strange that the Shogun in infected but the green gelato is not affected ? strange?
