watermelon seedlings are turning black and dying for some reason?
recently ive been trying to grow watermelons from seed, but for some reason at one point or another some leaves start to go broan/black and die off around the edges, and eventually it spreads until the whole plant inevitably just goes and dies.
i cant find anywhere on the internet about this, or anyone else having this problem.
one thing i should note is that these seedlings (and two established plants over a meter long) are in pots and containers when this begins to happen. is it just them dying from a lack of nutrients? in which case should i just me planting them directly into the soil once they have reached a certain size?
the same thing seems to be happening with various species of watermelon, please help!
