Sour 60/berry Ryder tent grow

So it's week 7, still haven't done anything much different, I'm having yellowing issues on one of the sour 60 girls and I just can't figure it out at this point, despite the yellowing she is growing and producing buds nicely so I'm just gonna let her go and see what happens. Splitting a gallon of water between the 3 every 2-3 days and using half strength nutes every other watering. They getting a nice dank sweet smell and i have to say I'm surprised at how much fruitier the sour 60 smells than the Betty ryder, I was expecting the berry Ryder to be the stanky one but it still has a nice smell too.
