this week i noticed i was giving too little calmagic so i upped that back to what the bottle recommended because my last crop liked a lot less cal mag but each strain has different needs
That is interesting. I assume this is your 6th/7th week, correct? My 3 BB Kushes began showing some fast yellowing from bottom to top after I reduced the Grow nutrients to start feeding more Bloom in week 6. This strain seems to be quite demanding. I believe they are very similar to yours regarding their stage. I'll follow along. Looking great!
