Ppm for autos?

  1. The bud formula being used is a 1-2-2 Npk , with normal indicas and no co2 enrichment It can be pushed to 1200 ppm MAX , what would the max ppm for autoflowering plants be ? I know most of you would say slowly rise ppm and find out for yourself but the autos are hoping to grow up to be a breeding pair so must be in perfect conditions from day one to chop
