The Blackberry plants look very good. BB2 has recovered from a nitrogen deficiency and is putting out nice buds. BB1 shows strong flowering as well. The NLs are both farther behind.
NL2 started with variegation, and shows weird growth patterns with tons of small leaves. We defoliated it, since the leaves were packing together in thick masses.
NL1 looks pretty stressed in the area around and connected to the main stem injury. Luckily it has multiple colas even though they're shorter. Hopefully it will heal as time goes on.
Humidity is too low for this early in flower, so I'll try to bring it up a bit.
