As your plant starts to use energy to make buds you will get yellowing of leaves. How many leaves are affected right now?

looks like a nitrogen deficiency to me. keep the bloom nutrient levels where they're at, but try raising the nitrogen levels up a bit and see what happens. Also, the pH for your soil might be a little too low. I'd raise that up a little too.

A ph of 5.9-6.2 should be fine, if you have a kit see if you can get it up to 6.5. The nitrogen might be getting locked out

It looks like it is defintely nitrogen deficiency, a lack of nitrogen is easy to spot; the plants yellow in an almost uniform manner.
