African Violets and Gesneriads: Strep & Kohleria dying? Leaves curled?, 0 by raisingsouls

I bought these about one month ago from Violetbarn.com. I bought about 35 plants. Most are growing. Many have buds, and I'm checking on the buds about 35 times a day to see when they'll open up into flowers!

About 5 plants have curled leaves, and the leaves feel kind of brittle. One strep's leaves turned brown on the edges, and I'm pretty certain that one cannot be saved.

Can these be saved?

I've been watering them very minimally, about aevery 4-5 days, and I have river rocks at the bottom to allow drainage. A few days ago was the first time I watered with a bit of DynaGrow fertilizer in the water, but this curly problem began about 2 weeks ago.

Thank you,

Ellen

PS- if the plants can't be saved, can I root a leaf and get babies, or is it too sick?
