when I see what you describe on my butterfly plants like passionflower it's baby caterpillar poop (correct name is "frass"). So maybe you have a caterpillar, probably not one you want, if you also see leaves eaten. Look on the underside of the leaves for critters. BT, bacillus thur-something-us, an organic pesticide will kill them.

Those black specks and the patterning make me think of thrips. Do you think that that might be a possibility, Larry?

Josh - The plants I have under lights for the winter get fertilized each time I water with 1/4 tsp of FP 9-3-6/gallon of water. When I water, about 10-20% of the total amount of water I apply exits the pot. If your plants are getting natural light and you think they could do with more, you might try fertilizing at the strength I mentioned, then water twice so you're flushing the soil, then repeat.At these low doses, there isn't much concern about over-fertilizing unless the soil is VERY dry. I'm watering well before there are any indications of drought stress, and have seen 0 indication of plasmolysis in any of the plants. Keep in mind that plants make their own food - glucose. Fertilizers are the building blocks they use to grow and keep their systems orderly. Charles - There is a difference between air movement and a cold draft or a hot wind. Air movement upsets the boundary layer (of air) surrounding the leaf and increases transpiration. This means that more nutrient solution is moved through the nutrient stream - generally a good thing. Air movement can also have a significant impact on keeping pests and diseases in check, and it helps promote back-budding. On the other hand, if your plant's ability to move water to distal parts is limited by poor root function/health, air movement can be a negative insofar as the plant's appearance goes, because increasing water demands combined + an inability to efficiently move water to the plant's distal parts will produce more necrotic leaf margins or tips. I have 2 - 20" box fans (set to low speed) in my grow area + a 12" round fan blowing over a plastic cake pan cover ($1.50) that holds 2 gallons of water with humidifier wicks in it to increase humidity, which really decreases the humidifier's run time. Too, MG soil has water retention issues you need always consider because of how water retention impacts root health/function. How much/often you water is always a consideration when you're using a water-retentive medium. Al

It certainly looks like mites. If indeed it was mites the damage was already done before you sprayed. The fact that you sprayed Trilogy (which is a neem product) and soap does not remove the damaged from the leaves. Your leaves will look like that probably for the rest of their lives. If the mites are gone the new leaves will look normal. You might consider starting a regimen to walk your grove to carefully inspect for any potential problems at least weekly. It is also a good idea to start a data base of any problems, where they occurred, what time of year, the date the problem was noticed, and treatment given and results. Many growers feel that by doing this they get a heads up of what to be on the look-out for during each season.
