Is this nitrogen deficiency or something else?Hello everyone! One of my plants has some fan leaves and new leaves yellowing at the bottom (and some are crispy). The plant is very bushy but from what I understand this could be nitrogen deficiency but wanted to check. The other plant is smaller and doesn't have yellow leaves
