Why are my plants turning yellow?
One of the most frustrating things is when you work so hard to maintain and care for something and it doesn’t end up perfect! Here at Ambius we have methods to help keep your indoor plants from turning yellow and can help you keep your plants happy and healthy for a long time.
Here at Ambius, we are able to chat with our horticulturalist, Matt Kostelnick, to ask him why this is happening. He said that it is very common for leaves on plants to turn yellow due to stress to the plant, which can be caused many different ways. Since this is such a common topic for prospective green thumbs, our experts thought they’d share what we have learned from Matt on how to prevent indoor plants from turning yellow. Here’s to keeping plants happy and healthy!

The most common reason that plants’ leaves turn yellow is because of moisture stress, which can be from either over watering or under watering. 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.
On the other hand, over watering can contribute to the leaves turning yellow as well. If you feel the soil and it is too wet then you know that you have been putting too much water on the plant. In this case the solution is simple in that you should not add as much water or water less frequently.
Another common reason that plants’ leaves turn yellow is because not enough light is reaching the plant. This occurs because the rate of photosynthesis is limited in low light, but as the light is increased, photosynthesis increases as well.
The temperature contributes to the color of the leaves as well, when it is either too hot or too cold. In terms of the cold temperatures, cold drafts on most tropical plants will contribute to the yellowing of the leaves. If it is not periodic temperature change like a draft, the leaves will most likely be brown if they are exposed to prolonged cold temperatures, especially when they are positioned near an air conditioner.
The yellowing of your plants can also be a good indication of their nutrition. Specifically, if there is an strange pattern to the yellowing, like if the veins on the leaves are green and the tissue is yellow then it is almost always a nutrient problem.
Common sources of nutrient issues are under-fertilizing or over-fertilizing, so it is important to use fertilizer at the labeled rate.
Frequently people tend to use too much fertilizer on their plants to make them grow faster, but what it actually does is create a toxic environment which “burns” the leaves out causing them to turn yellow.
In addition to the problems listed above, other conditions that lead to the yellowing of the leaves include infectious diseases (fungi or bacteria), poor soil, natural aging of the plant and plant destroying pests.

4 Reasons Why Your Pot Leaves Are Turning Yellow
There are several different reasons why your pot leaves are turning yellow. A variety of factors cause chlorosis, the technical name for a reduction of chlorophyll that results in yellow leaves. This isn’t a definitive list; however, it’s always important to properly diagnose an issue before attempting to solve it. So here are four reasons your weed leaves are yellowing—and how to deal with them properly for a heavier harvest.
Not Enough Light
During photosynthesis, leaves take in light and carbon dioxide (CO2) and convert it into plant energy. Without enough light, leaves will begin to yellow and eventually slow growth to a standstill. Common incandescent house bulbs are severely insufficient, and fluorescent lights must be kept quite close to plants to be remotely effective.
The Fix: Increase the amount of light the plant is getting. This could mean lowering an existing grow light to the proper level above your plants’ canopy or investing in a stronger lighting unit. I highly recommend using HID (High Intensity Discharge) lighting, such as MH (Metal Halide) or HPS (High-Pressure Sodium) lighting for growing pot plants indoors. LED (Light Emitting Diodes) and Compact Fluorescents are a decent, if not perfect, alternative if heat or power usage is an issue.
Over or Under-Watering
Marijuana plants like a wet-dry cycle for their roots. Over- and under-watered plants will droop and soon show the telltale signs of chlorosis.
The Fix: Stop watering over-watered plants and increase watering for under-watered ones. Sounds easy, but it’s one of the most common mistakes beginner growers make. Lift your containers if you can to get an idea of what they feel like when soaked and how much less they weigh when dry.
pH or potential hydrogen is the measurement on a scale of 1-14 of the acidity or alkalinity of a soil mix or nutrient solution, with 7 being neutral. Soil pH should be kept between 6-7, while hydroponic pH should be 5.5-6.2.
Fluctuations outside these parameters will lead to nutrient lockout, preventing your roots from being able to take in food. Often misdiagnosed as a deficiency of nitrogen or iron, an undetected pH imbalance can compound problems further when more nutes are added. This creates an over-abundance of plant food in your root zone that your plants cannot absorb.
The Fix: Use a pH meter to measure the level of acidity or alkalinity of your soil and nutrient solution. Adjust using pH up or down accordingly. Bear in mind that these solutions come in concentrated form, so add them sparingly to raise or lower pH incrementally.
If all other factors are in balance—light, water and pH—then the most likely culprit is a lack of food for your plants. Nitrogen and iron are the most common deficiencies that cause yellowing leaves, but it could be any number of macro or micronutrients as well.
The Fix: Water with a nutrient solution high in nitrogen. Plant food bottles typically display NPK ratio on the labels. N is for nitrogen, P for phosphorus and K for potassium. Choose the nutrient with a higher number at the beginning. They’re labels will say “Grow” or “Vegetative” as opposed to “Bloom” or “Flowering.” If you decide you have a lack of iron, foliar feed with chelated iron. You should see your leaves greening up within a few days.
