Watering is ambient in this weather, Davy. The heavens provide what they provide. It's not been overly wet, a few showers every couple of days. Cloudy, but not overly rainy. Temps at about 12-15C day and night.
Some plants are against an east facing hedge and others a west facing green house. My prevailing wind has been easterly at the moment. That means the hedge ones skip a little natural watering and the GH wall ones get the full whack. Both are suffering. Compost is always moist, not wringing wet, just moist. If it was dry to second knuckle depth i'd water but it's never come to that.
Definitely have leaf curl! This is Scotland in one of the coolest summers I can remember but I thought leaf curl was pretty much harmless. Can it cause little spots of necrosis and entire leaflets to brown and crisp?
The lesions are all over the leaves except for the very newest embriotic ones at the growing tip. Pics aren't too great, really. I'll post some better ones tomorrow. Bit late now and better taken in sunlight.
