FF learners will smell like fruit punch with some orange and will turn purple . The green phenos of PD are more potent and had orange/punch on the inhale and some cleaner on the exhale. This was my experience anyway
I started spraying 5 days before I initiated flower and then every 4-5 days until about day 24-28. Basically when I say balls forming I stopped. It was probably 5 sprays total
I think it’s strain dependent tbh. My reversal did t dinp pollen like a traditional male. Some just need to be milked. I used STS spray from HydroRed and sprayed every 4-5 days
