I put some wood mulch around the one in particular, actually. I NEVER water from above. I actually hand water everything using a handheld gentle shower arm and directly onto the soil/mulch. There are only two plants that have this issue and they were not next to eachother. I have a very healthy and rapidly growing Krim that was next to the one in the pictures that has no spots, bad leaves, etc... anywhere. I would think if it was from watering or the rain that it would be on several/many plants. I have a total of 60 tomato plants and two have spots on the fruit and three have/had what appears to be septoria leaf.

I've seen the damage leaf miners do on tomato plants but this looks so different to me. That's why I thought this might be a fungal or bacterial disease. Leaf miners don't usually leave the black centers like this at early infestation, just their tunneling "trails". But you might be right.

stress related to receiving them 2 weeks ago .. and perhaps even from when the local seller got them from the grower ... and the mailing itself on the other ... and you cant seem to keep your hands off them.. wiping them down ... all leading to superficial leaf damage ... until it falls off... a leaf can still do its work if it has any green ... just water properly.. and in a month or so.. they should settle down ... they are not houseplants.. i hope they are going outside in full shade for summer ... they are stressed.. not hungry.. fert is not rec'd .... ken

What you've pictured is a 12 volt male "plug" with USB sockets on the back side. There are many, many kinds of electrical do-dads, ranging from spotlights to tire pumps to vacuums to coolers , fans and what not that use 12 v male plugs (but without USB slots) for the connection to the 12V sockets often found in RVs and boats as well as cars. The socket used to be called a cigarette lighter socket in cars, now just 12 v. Cars always have one or more. Those work, of course. The limitation you have with using a thumb drive in the car's USB slot for audio books is this - there's no way to have personal mobility to listen to the book when you leave the car. Imagine a Kindle or book copy that can't be used outside of a car. And when you remove it from the USB socket, you lose your place. For those for whom reading a book is a continuous process of repeated sessions, one of which may be in a car but the next one out of the car, audio books are more easily listened to if on a smartphone (and most will play in the audio system over Bluetooth) or using a small MP3 player. I choose the latter, they're smaller than my smartphone and I can use them all over. If they fall or get damaged, I don't worry about them because they're inexpensive. Sandisk still makes and sells MP3 players. not sure for how much longer. WIth a spring loaded clip on the back that will clip onto your top when exercising, working indoors or out, etc., that you can use cheap earbuds with. Go in the car, use the 3.5mm cord instead. Leave the car, disconnect, plug ear buds back in to keep listening. Lots of choices, each with advantages and disadvantages
