Is my solution too mild ?

[Flora]

Hi Ron. I have new chrysanthemum cuttings in a 11-Plant for a week with a mild nutrient solution of GH Flora with 15 ml of each part for 5 gal. The new growths are VERY twisted and deformed. The cuttings are from a chrysanthemum in soil, which has no problems like this !!! Is my solution too mild ? Recently, I've moved and my new house is in a "hard water" zone and my previous was in a "soft water" zone, but I use my "old" soft water nutrients. Can I have a problem with this. Thank you for support.
