Help! any ideas why are we having this problem?

Hey guys,
we are close to harvesting our plants (1-2 weeks left I think), but we have one problem. The leaves of the plants started turning yellow and we cant figure out why. any ideas? I am thinking about nutes deficiency, although we are feeding the plants every 7-10 days with complex flowering nutes (5-10-10) but they look to be low in microelements like magnesium and etc. since I'm not sure about this, maybe some of you got an answer?
thanks in advance!

what?
at the very end of your grow, when the plant is near one eating, and your perfect nutrients are being metabolized correctly...a few fat fan leaves turn yellow and you're concerned?=crazy

skip a feeding or two before you harvest for best results.

thanks for the answer. so you think everything is ok with the plants? I'm thinking about feeding them now with flowering-veg mixed nutes, to give some more nitrogen for the plants. can this help?

sure, if you want to taste overfed fertilizer bag weed, go for it.
I'd skip the last feedings for best results, and extra N in end flower is an ill habit
check out an ed rosenthal book for a better understanding of
plants and their finish
yellow leaves do not turn green when fed N

This is a pretty natural thing ,you may be thinking of your harvest but the plant is ending it's life so ,being this close to finish of flower you will see some leaves loosing color or yellowing up ,each plant may vary a bit but is normal ,you should be getting ready to flush which will yellow mor leaves as you flush the nutrients out of the soil in the last weeks ,Just keep a eye on your trics and harvest when it is best for you mate
