the other day i pinched the top of my tomato plant as i felt it was getting to tall and wanted tyo focus the growth on the tomatoes. the next morning the top two branches really close to where id pinched had curled in on itself similar to what a fern looks like as it sprouts. now from what i read i could have a virus of some sort, but the thing is there is no sign of any damage or illness. the flowers have carried on blooming, the plants got thicker and more robust,the leaves havent changed colour and the curliness is still on the top two trusses and no where else. and its been about a week since it happened. the soil is moist so its not underwatering. theres a chance its overwatered not because ive watered it too much but because the tub its in has no drainage holes and ive noticed the soil not drying out despite not having watered it for a week. given the timing of when it happened could this curliness be caused by pinching out? or is it more likely over watering, viruses or another reason? any help apreciated. its in close proximity to alot of other plants
