more newb posting here. my first year centennial has some kind of issue. the lower leaves have started turning black, starting at the tips and creaping towards the stem. i'll try to get pics when i get home, but i don't know for sure that my camera works. additional info: it's planted in a cedar planter with tons of drainage. i don't think it's been under or over watered. no signs of bugs at all. the soil is a mix of vegetable potting soil, homegrown compost and chicken manure.
diseased centennial?

as promised, photos!
and, not as promised, one more grumpy-looking hop.
this is on the mystery hop, any it's got this white crud on it; this is the worst leaf i saw, but it is evident through the bottom half of the plant.
i have been applying insecticidal soap due to aphids, so it's possible that it's residue from that, but it doesn't seem to wipe off

I'm guessing you're watering and/or spraying the insecticidal soap when the sun is shining?

no. the soap is going on in full shade when the chance of sun for the day has passed. it is not sunburn.
the centennial with the black spots has not been getting soaped, as there have been no insects on it (fingers crossed).
the centennial has only been getting water (rarely necessary around here right now, and only after sunset) and superthrive on occasion.

the white stuff or the black stuff?
the part where it looks like someone took a torch to the side of the leaf.
