yellowing leaves on bottom of plant working its way up

So i am about 1 week or so into flowering and the leaves on the bottom of my plant are turning yellow and falling off....i dont think its a nute. problem but maybe im wrong...i will post pics of if need be but that is really the only problem...

higher nitrogen would keep the leaves from falling off so fast.

It may not be a over nute problem, but it may be a lack of nute problem. yeah pics would help too. Also what nutes your using and what concentration.

well this is my first grow using a 400 watt hps and i have three babies under it.....im using a 15/30/15. it some cheap shit that i got from the store(not MG) but it seems to be working out. But nitrogen should not be the issue because i had some worm casting that i mixed in with the soil when i first trasplanted them....
