gravity flower hardener possibly making leaves turn yellow?

I used gravity about a week ago and my bds have bulked up consideably and have indeed "hardend". My hydro shop guy told me it causes a "massive nutrient uptake" so im wondring about the yellowing of the leaves. And should I be cutting off these older laves that are turning? And my plant is getting chopped june 21. so 9 more days.

god damn! Gravity is amazing!!! Plant is yellow as fuck though.

Yellowing leaves are normal when harvest gets close. Nothing to worry about. Hope you reap a good harvest.
