Looking for help with my monstera. New growth is coming out as stems with brown tips and no leaves. This happened in both of my main stems-thought it was just a 1 time thing but now a new stem has popped out of 1 of the bad stems with the same issue. She gets mostly east sun. I water about once a month/only when the soil is dry. Ran into a probablem with thrips a few months ago but sprayed it with neem oil and thought I had gotten rid of them.
