my baby plants are really lanky for their age. its not due to lack of sunlight cos they're in a position that gets at least 6 hours direct sunlight a day. theyre only 10 days old right now. ive never grown before so i dont know if this is usual behaviour. if it is normal when will they start to thicken or grow more leaves, as they only have 4 at the moment (2 round, 2 spikey)
