To day was warmer than yesterday was 22, today 23. Will check in sun temps tomorrow..Looks it to me. Whats your temps in direct sunlight?? Mine taco up with temps in mid 20's c (in the shade) 30c+ in direct sun. Nowhere near that though, and they're always flat again in the morning.
Going to pull one problem plant, dig out a planting hole and put in some potting soil Then put in a replacement seedling just a week old and see what happens. Good luck., thank you for your help.As it's outdoors, just let it go and see what happens. If it dies it dies.
I got a couple that don't seem to be growing well (half the size of the others). If they were costing me money i'd ditch them, but as sunlight is free I'll just let them go and see what happens.
