2. Lightning Issues
Lightning is a curial need for your Alocasia plants. When light exposure is not enough, Alocasia plants are bound to turn yellow. They are sometimes known as low-light plants as they grow in tropical shades.
However, the lightning in forest conditions is brighter than in most indoor conditions. If they are indoor plants, you should place them close to a bright window and ensure to protect them from intense sunlight.
Changes in seasons could also set in. An Alocasia plant that usually blooms near a bright window could start to have issues as the autumn light conditions dwindle. If you notice pale or color changes in your plants, you should move them to a brighter spot.

The decline and yellowing of your Alocasia leaves could be signs that your plants need a warmer location. Alocasia excels in warm conditions and, they do well in temperature ranges of 18°C and 29°C.
These plants cannot tolerate frost conditions and, they begin to suffer in temperatures below 13°C. If your indoor temperature is way too cool, your plants might not have the warmth conditions that they need.

Alocasia is a humidity-loving plant. But, they could grow in low humid conditions. They best prefer levels above 60% or 70%. The yellowing of their leaves with brown edges or tips could be a symptom of low humid conditions.
This color change happens gradually in the leaves all over the plants. The safe humid region is 50%, even though some growers have seen the plants grow in levels below.
If the humid conditions your plants are in is below average. You can step it up by grouping the plants with other tropical plants.

A lack of nutrition could also be one of the reasons why your Alocasia plants are turning yellow. They grow well in warm conditions and, feeding them every two to four weeks will do a lot of good.
If the nutrient levels start dropping, they accelerate the retirement of aging leaves to use the resources.

If you have not made use of fertilizers before, you have to work out a feeding plan. But if you have made use of fertilizers, continue with your plan but step up the quantity a little.
Monitor the leaves carefully for weeks after you have applied fertilizers. If you do not see any notable changes, go back to the former feeding plan and check other factors that we have aforementioned.
If you notice an improvement, however, continue with the correct dosage. Do not keep increasing if you don’t notice any improvement.

Alocasia plants could easily be affected by common pests like thrips, aphids, spider mites, and scales. The big, juicy, and soft leaves are a big attraction for pests at any time, so you must endeavor to check your plants often.
