Hi All

See the attached image showing a problem I have on the tip of some potted citrus leaves. Leaf with black/dead tip.

Whilst this isn't a very new leaf, the issue which is well illustrated here on the tip is consistent with what i often see on small new growth leaves. Not all new growth but quite regulary.

Some tress are in 5-1-1 and some in off the shelf mix. Both types are having this problem it appears.

I have sprayed once with a organic pesticide. Although I can still see some very very small insects on leaves and some webs.

Possibly spider mites?

Any ideas?

Thanks in advance.

Cheers
