Adopting Eleven Roses week 1 flower

OK so update from last week I found out my soil is really off pH it could be 8 or 9 pH but I haven't got a soil meter to be sure. Anyway, obvious massive deficiency in ll kinds of nutrients because their roots can't soak up anything with such alkaline soil. I did think about reporting them and trimming their roots but it's too late in flower for that and I don't have the time. What I have done is I am using PK 13 14, Cal Mag and home made spray from organic waste mixed together as a foliar spray per guidelines. The one in the right is terrible she isn't taking it well at all I've had to remove 90% of her old leaves she looks like a skeleton but on the up side the new growth is green and happy so I'm just taking off the old as it shrivels. The one on the left is a tough mofo and sprung back after 2 foliar sprays (once a week) though I can definitely see a PK deficiency still. I am still hoping the one on the left will make it while the right one might bounce back but I won't get much from her. Anyway guys if you have any tips for what else I could do for my ladies to help it would be much appreciated!
