Alocasia nebula brown and yellow edges
One of the leaves on my poor alocasia nebula is suddenly starting to brown. I don’t want to lose it :(

Any idea what kind of an issue it is? Soil mix is perlite and easy draining. I water it every 3-4 days but have a water meter and let it dry completely between waterings. Kept at 60-80% humidity and around 86 f / 30 c.
Potassium deficiency may be the culprit if you haven’t added nutrients.

A common problem with Alocasia and almost all indoor houseplants is what we call “tipping” or simply the tips of the leaves drying out and turning brown. This can be caused by a number of factors including over-watering, chemical burn from too much fertilizer, Root rot and dry stagnant air.
@Gordo @sarahsalith any ideas?
@GoodIcarus I’m just guessing as you’re humidity and temperature is great, but I’m thinking under-watering. Allocasia do like to be keep a little more moist so maybe not let it dry out as much. The coir pot may not be helping as this will let it dry out quicker. Maybe try to pot in a terracotta pot or up the watering. Is it a new plant also as it not showing in your plants. Just as the other thought was if new, then maybe check the roots. Was the leaf mushy or just crispy all the time?
@Gordo thank you for your wisdom.
@Gordo thank you. It’s about 3 months old, it started to brown around 2 weeks ago. I was struggling to know if it was over or under watered, but assume it is a water problem. Leaf is crispy/dry as opposed to mushy and wet.
@KikiGoldblatt thank you!
@KikiGoldblatt no problem. I was looking at this when you posted. I was trying to think about it as the leaf and the pot was thrown me of. My allocaia like it to dry out but not completely if that makes sense. They love to drop a leaf as it grows a new one.
@GoodIcarus great then maybe water a little more to see if that helps. Mine are in terracotta so I get the the soil to not stay wet but it gives me a few day’s that I can water or not water and the plant doesn’t show any stress. I only getting 60-80% humidity also so similar conditions. I hope this helps and you do well with the plant as they have stunning foliage. I have thrips and spider mites at the moment so keep a eye out for pests on theses!!
