Generally when a houseplant leaf turns yellow, that leaf is dying. Chlorophyll gives a leaf its green color. When the leaf loses its chlorophyll, the plant abandons it and begins to absorb leftover nutrients from the leaf. That's why once the leaf turns yellow, you generally can't make it turn back green again.
A leaf that turns completely yellow has lost its chlorophyll, so it won't turn green again, even once you fix the issue at hand.
Once the leaves turn yellow, or start yellowing, they cannot turn green again. I would recommend chopping the yellow leaves and getting a moisture meter. The most common cause of yellowing is watering issues.
Whole Plant Yellowing or Semi-Yellowing
The solution is to repot to a bigger pot and provide fresh potting soil which contains nutrients and organic matter. If you find your plant still has room to grow in its current planter you can fertilize your plant instead to replenish its supply of nutrients.
Miracle Gro or any high N soluble plant food will help with that.
The most common cause it a lack of magnesium in the soil. Epsom Salts helps correct magnesium deficiency, mix 30g of Epsom Salts per litre of water (approximately 2 tablespoons), per tree. Alternatively, Epsom Salts can be applied directly to the soil at the same rate, water in well after application.
A mineral deficiency that often causes yellowing is iron deficiency. Iron is essential for the production of chlorophyll, the pigment responsible for the green color in leaves.

Known as a garden helper, Epsom salt is a natural and effective way to provide essential minerals to plants.
Fertilize: The most effective way to prevent and treat nitrogen deficiency is to fertilize the soil with a nitrogen-rich fertilizer, such as urea, ammonium nitrate, or fish emulsion.
For mixing olive green, take a good amount of primary yellow and add a tiny bit of cobalt blue to it. This will result in a deep olive green. If you want to lighten it up a bit add some titanium white to create a light olive green.
Overwatering means yellowing leaves, a general feeling of flop (science calls it wilting!), fuzzy soil, and a pot that feels like it could double as a weight. Underwatering shows itself with crispy leaves, that same sad droop, and bone-dry soil.
The three major nutrients plants need are nitrogen, phosphorus and potassium. Nitrogen is the main nutrient that supports plant growth. It makes plants green and leafy. Provided at the right time and in the proper amounts, nitrogen can give plants the kick-start they need to produce a bountiful harvest.
Prevent Fungal Disease
MAKE IT: Mix 1 teaspoon of baking soda and 2-3 drops of liquid soap in 1 liter of water. Spray the solution on the infected plants. Baking soda helps the plants become less acidic and prevents fungal growth.
Are coffee grounds good for plants? Coffee grounds are an excellent compost ingredient and are fine to apply directly onto the soil around most garden plants if used with care and moderation. Coffee grounds contain nutrients that plants use for growth.
Saturate the soil with 1/2 cup hydrogen peroxide 3% per 1 litre water. Put wet soil in a watertight container and leave overnight before planting. This kills pathogens such as fungi and bacteria including insect eggs and nematodes (roundworms).
If you have a plant that has yellow leaves, check the soil in the pot to see if the soil is dry. If you believe that the problem is due to under watering, water the plant more often and consider letting the pot sit on a dish to recollect any water that has overflowed, so that the roots can absorb the extra water.
Nitrogen deficiency shows up as a general yellowing. Older leaves closest to the stem turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves. Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green.
Yellow leaves on plants don't necessarily mean the overall plant is dying. Sometimes, older leaves turn yellow and shed. If the cause for yellowing is reversible and the plant is otherwise healthy, then there's no reason to think the plant is beyond repair.
The best fertilizer for plants largely depends on their specific needs. Generally, a balanced fertilizer containing equal parts nitrogen, phosphorus, and potassium (NPK) can provide essential nutrients for overall growth. However, it's crucial to consider factors such as soil type, plant species, and stage of growth.
Yellowing Leaves: One of the most common signs of overwatering is leaves turning yellow. While older leaves will naturally yellow as they age, widespread yellowing, especially in younger leaves, indicates excess water. 2. Wilting: Paradoxically, overwatered plants often wilt, much like underwatered plants.
