Help! Two of my plants are going through similar problems. My mint is yellowing at the tips then turning brown shortly after (falling off while mostly yellow). This has happened twice now, once with a potted pretty large mint, which I took a good cutting from then propagated trying to same any of it. The mother plant died but the propagation has stayed strong. Until now, when its beginning to do the same thing. It has full light and is still in water? I've never had issues with mint before so a bit confused. The second plant is a small Monstera, it's in a mixed tropical soil from a friend and a terracotta pot, watered on schedule and partial light but I just keep getting yellowed leaves. Pictured are the second and third leaves I've had that have gone completely yellow with no explanation.... anyone have a clue?
