Help! lower leaves started turning yellow

[GarciaGrows]

Can anyone identify what is going on? Tomorrow this 24K Strain will be in week 6 of flower and at week 5 I noticed that the lower leaves started turning yellow but now it seems like a bunch of leaves are turning. I water with pH water and molasses mixed it. I added less than 1/3 cup of bone meal about 2 weeks ago. We use organic soil and we don't like using synthetic nutrients. Our temps are fine but we just can't figure out what is going on.
