Hi! Newbie starting plants indoors for the first time.
I am planning on transplanting outdoors when the season permits (I’m in Ontario) and have started seeds indoors. I am growing in regular triple mix soil.
I noticed that the tips of the leaves on one of my plants is curling and turning black.
i am wondering if it’s a nitrogen problem or what’s going on and how do I fix it (as inexpensively as possible).
