hello

Who can help?

In pictures in addendum you can see Kentia leaves with chlorosis in different grades.

Has anyone of you already seen this symptoms?

They arrose about ten days after an acaricide treatmement with a flowable Pentac.

This product has always given a very good result with no risk for the Kentia.

pH in the substrate is low about 3.5 to 4.5 , Fosfate level is high 1.5 till 2 micromol.

What can be done to stop the further demolition of the plants, it is still in evolution 12 weeks after the first symptoms.

Any suggestions are welcome!!!!!!!!!!!!!!

Thanks in advance

Ignace Vanluchene
