I've got some concave leaf curl going on on my indoor tomato plant. I haven't found any images that resemble this condition. The plant itself is strong as heck, got really thick, dark green leafs, planted 30cm deep 14 days ago and with the main stem cut off a week after.
These are the images. They are 6000x4000 so zoom in as much as you want. My go-to culprit is too much water or too little. What do you think?
