I've had this plant since it was very small, about 2+ years. It grows new leaves bigger and taller than the last every other month or so. Although when new leaves grow, a smaller older one turns yellow and falls off... and now these dark dry patches are all over every leaf. I can't tell if it's over watering, under watering or something else. I water it once a week, every other week in the winter, and I put 2 white fertilizer sticks into the soil every 6 months. (Which I've done to all my plants but this is the only one with yellowing leaves) please help 😭

Images show a brand new leave that opened this week with small yellow spots already on it!

Alocasias are not easy indoor plants. Even minor lapses in watering will cause leaf discoloration. It looks like you have repotted yours so that makes providing proper watering instructions difficult.

Maybe I should repot with new soil. I was worried it might be root rot, but inconsistent watering was not what I expected. I thought i might be over watering that's why I would skip a week sometimes... do you think that might actually be why?

Repotting and replacing soil almost never fixes anything and usually make matters worse. Soil can just as easily get too dry as stay too moist. The key is to find the right balance. Because everyone repots differently, there is no way to know what proper watering for yours now is.

Did you remove some of the original soil when you repotted or did you leave the rootball intact? Does the new pot have a drain hole? How dry does the soil feel and how deep before you water? How much water do you give it?

Please post a photo that shows the pot and soil surface with the pebbles removed from the top.

Will,
I don't know if I'm allowed to join in here but..... mine was doing the same things. I'm glad I took it out of the plastic pot and put it in a clay one. Ever since I got it, 3-4 months ago, the largest leaf has dripping. Yes it had drainage holes. I dug a hole next to the pot and it was dry. So I gave it 1/2 cup water. This has been going on all this time. When I took it out of the growers pot, it was 3-3 1/2 of muck. Do u think I did the right thing?

I am not sure if Will is still here. I have not seen him in a while
