im a noob, but i doubt its the mineral oil. many people have recommended mineral and vegetable oil and claim it is safe with no problems. my avos were going south before i added anything. i tried vegetable oil for any possible pests, but it didnt help, but didnt hurt it any worse either. i guess perhaps if there was a tremendous amount of oil residue, it could be magnifying sun rays. but that sounds far fetched to me personally, but who knows.

Good job! You got the photos posted! Really can't help with the first picture, enlarge it so we can see it better. The second shot could be slug damage or possible bacterial. Could it have gotten sunburned and developed infection? Not sure on that one. Congratulations on the post, Jane

i doubt it ... more like individual cells burst.. which sometimes happens with excess rain ... i am pretty sure there is a tomato forum .. where the real T kooks hang out.. lol .. just keep in mind.. about 99% of that leaf is still functioning ... so at this point its only cosmetic damage ... and i am thinking.. those are the lowest.. oldest leaves ... what do the newest growth point look like ... that is where i look to see the vigor of the plant .. or the newest of the bug .. if any ... ken

No problem, thanks for the advice. I have noticed after a few weeks without much rain they start to droop. One even shed some old leaves once when I let it go too long. They bounce right back after watering once or twice though. But I will keep a closer eye on it in the future. i cut the shells in half, and then soaked them in rainwater for maybe a week? I changed the water every day or two. Then I packed the shell with lfs, and mounted them up. For the first month or so I watered every day or two. After about a month they had roots growing into the moss, and around the shell, and even into the material of the outer shell. At this point they have such extensive roots they don't show any signs of drought for at least a week, maybe longer, of heat and dry. I've been very happy with this. They've even grown better than some I have mounted on a tree. the one hard part is watering without splashing the crown. I used a hose carelessly at first and lost a leaf to crown rot. Caught the rot right before it spread into the crown, and cut the leaf off. i took pictures of the spots close up. I'll attach those now. The circular spots in particular concer me.
