look at the 'salt' rim on the side of the pot many pots like these suck up the water leaving the soil toxic with nutes just like this also the plant is too small for this pot hence it dries out too quick change pot study some more good luck
That isn't salt on the side of the pot, lol. You really think there is a sodium build up on a plant that young? I would bet my left nut that is calcium deposits from the water. Plant is too small for the pot? Huh? How did you even come to this conclusion? You do realize in nature seeds sprout in fields, right?
