Eutrophication, nutrient deficiency or spider mites?

You choose to ignore PH at your own peril...You cannot properly diagnose a plant problem and NOT know the Ph of the water/nutes you feed it, the soil Ph, and the runoff Ph. If you want help, listen to the peeps like Shov that truly know and have experience with these weeds! And stop spraying soap on it...it's only making things worse, and not solving a thing. Ck the Ph and you will find the problem...start checking (and properly adjusting!) the Ph and you may save it.
