Espoma Potash and soil acidifier Fast or slow?

I need a quick solution for my roses, but the soil test said that I am deficient in Potassium and my soil is 7.7 for the pH. The problem is, in the meantime, what can I do to help the roses? I have already broadcasted some Espoma Soil Acidifier and some Espoma Potash over the bed, but they may be slow acting. The leaves are turning browned on the outer edges, and it looks like on of the new shoots on Westerland is not turning green, but staying red!

Can I use a liquid potassium and a liquid soil acidifier sort of as a drench? Maybe the Greenlight soil acidifier? I'm not familiar with the products and don't know if it will burn the roses and clems. However, my iron levels in the soil are already high enough, but the plants can't utilize it I guess.

Here's a link for the liquid organic potassium:
