Here is a shot of one of my Hallertauers. They were both doing rather well until a wind storm a couple of weeks ago knocked them off their ropes. Actually, all the plants started having trouble around the same time. You can see how the newer growth is quite pale. Interveinal tissue of the young leaves is almost transparent.
Closer shot of same plant showing pale yellow color, and curling of leaves. Also note underdeveloped/burned center lobe. Before finally drying out, tips would be dark green/black and would seem overly "wet".
The Sterlings are, by far, faring the worst. Overall shot showing yellowing of new growth. Older leaves tend to be paper-like rather than supple. Growth is rather stunted.
Closer shot of base of plant. Older lower leaves on most plants began to show mottled chlorosis which eventually became necrotic. The color in this photo doesn't truly illustrate the lightness of the younger growth (see previous picture and pictures of Hallertauer). Note how in some of the leaves the veins are darker than other parts of the leaf. This characteristic shows up on the other plants as well. It's not apparent in this picture, but many lateral growing tips on most all plants have some browing on the edges of the emerging leaves. All but one of the growing tips in this picture are actually laterals/side arms from the original bine - Another trait just about all plants share.
