Comment to 'black spot on rosa's'
  • Depends....Is she still showing normal growth? Seeing any bugs? What is the temp and RH?

    When I seen your pick I was amazed at how much it grew very bushy too, my opinion is if your past week 2 in flower I would thin her out to allow better air flow if fungal should help maybe lower your RH if possible, and I would also think about increasing your cal-mag how many ml's is she getting now?
