I planted 3 seeds about two weeks ago but only 2 germinated they seem to be growing well but now theyve got small black patches on their leaves and theyre kind of curling up and going crinkly what is this? is it some sort of plant disease?? can i do anything about it??? Also what are the best conditions to be growing them in cos at the moment theyre in a small glass jar indoors but really theyre getting too big for it already. I dont know all that much about growing plants at all so any advice would be appreciated. Thanks!
