PGR and AMS spray together?

I would do them separate. I spray my PGR with urea with no issues but you’re going to want to water in the AMS immediately while you’ll want the PGR to sit on the leaf for at least 30 minutes. I can’t speak about the citric acid but you’ll be lowering your pH with the AMS as well.
