Normally, I'd say yes, go for it. But looking at your grow..I wouldn't want to mess with anything WHATSOEVER. Just let her finish eating up all that goodness, normally on a synthetic nutrient run you'd be winding down now on the nutrients. And your mix is perfecto. I really would consider sticking with what you are doing atm cause that mix is tops.
Experiment on your next round to see if it adds anything. But for the grow. She ticks all the boxes, nothing needed but let her finish off as she is.
Happy harvesting, enjoy the rest of the fattening period.
