My Thai basil is turning yellow. (picture attached) Has anyone encountered this problem? According to the internet, it is one of the following: 1. Root rot from improper watering. 2. Fungal disease - Before it sprouted, it looked like there was white mold growing but AG's site said that was good mold to help it grow. (I have a picture but the message will only let me upload one picture.) 3. Chilly temperatures - My apartment is 70 F. or above during the day and no lower than 65 F. at night. What should I do? Should I transplant it? I only have coco coir. Attachment Deleted |

I forgot to mention that it is in the same unit as a tomato, two lettuces and two pods that haven't sprouted yet.

How big is your tomato plant compared to your basil? Did you start the basil much later than the tomato?
I've seen my thai basil turn pale when it doesn't get enough light, but I see that the tips of the leaves are starting to dry out as well, which makes me think it might be a nutrient deficiency.
(don't go adding more nutrients to your AeroGarden just yet though)

(don't go adding more nutrients to your AeroGarden just yet though) They are about the same height because I pruned my tomato down so I wouldn't have to raise the light. A tomato, 2 lettuces, mint and basil were all started on 4/10 but the basil was the last to sprout. Tomato and Thai basil are on opposite sides of the unit. The basil is next to a lettuce. The lettuces sprouted first and tomato followed a few days later. I trimmed/ate the lettuce leaves next to the basil everyday to make sure the light would not be blocked. Have checked to roots and there are no black roots. Color is the same as other roots in the unit. I cleaned my unit on 5/8, added nutrients, removed the mint because it wasn't mint and added another tomato and mint pod. I forgot to hit reset on the nutrient light on 5/8 but did it on 5/9. Now that you mentioned nutrients. I just realized I forgot to add nutrients yesterday. But would that make a big difference? Attached is a picture of the Thai Basil before it sprouted. You can see the mold growing inside the pod. Attachment Deleted |

I have never grown Thai basil but it should not be much different then others. Let me start with the "mold" picture. That is a white fuzz that is not harmful to the plant. See more about that in the first post here. As for the yellowing, it may be the nutes. Tomato plants from what I have read will uptake nutes faster then the herbs. I have no idea if this is true however. Is the water hot? I know herbs like cooler water while peppers and tomatoes prefer warm. Maybe just snip those leave off and see what happens. |

I agree with Shawn. Remove all the yellowed leaves and wait a while. The tomatoes might be using up nutes the basil needs.
If the new growth comes in green, it should be fine. If the new growth doesn't thrive, you can decide what to do then.
When a pod doesn't do well, it is not necessarily your fault. Some just don't do as well as they should. I've lost a few.
If you do switch to coco coir, you can feed it the same hydroponic nutrients, although it would probably do better in container potting soil with a little fertilizer. You could also use up to 1/3 coco coir in the soil to keep the soil loose and help with water retention. But if the plant is sick, transplanting probably won't help.

There is new growth on the bottom but the leaves are yellow as well. I ordered some potting soil so I can transplant it. Hopefully, it will recover. Thank you. |

The water is not hot. It's room temperature. There's new leaves on the bottom but they are yellow. I'll try snipping off some leaves and see what happens now that I've just added nutrients. |

Growing thai basil right now as well and have grown it in the past. My yellowing was due to not enough light.
When you transplant, I'd set it hear the light source as most as possible. I kept mine alive for almost a year after transplanting (it was a beautifully woody bush in the end!) but was out of town for a few weeks and my partner managed to kill it (the second basil he's killed on me lol!)

It's definitely getting enough light. I trim the lettuce next to it daily. I think it needed nutrients. After I added nutrients and trimmed the top and some of the yellowing leaves off, my basil seems to have revived. Also noticed a little growth spurt. Maybe I didn't put enough nutrients in last time...? I also pruned my tomato as well. |

Just wanted to update everyone on this in case it happens to someone else.
After I added the nutrients, the leaves turned greener. Sadly, about 1 1/2 week after, the leaves started to turn yellowish again. So I transplanted it into a self watering pot with coco coir and nutrient water. It's now getting less exposure to light as it's sitting next to the AG instead of under it. But it's started turning greener. I think planting Thai basil in the same AG as tomatoes may not be a good idea, especially when the basil sprouted much later than all the other plants in the unit. I thought about adding extra nutrient than recommended but worried it might burn the others so I decided to transplant the Thai basil. Since it took such a long time to sprout in the first place, I'm assuming it's a little weak compare to other plants. (Is there such a thing as a weaker plant?) I hope having it's own source of nutrients will help it to grow strong. :-)

Some plants can grow "weak" At least I have had it happen.
Also, Something I noticed with my own garden is that lettuce takes less nutes then herbs. I use only 3-4ml nutes in lettuce and keep my herbs at 6ml. That is what works for me. I also think the type of water you have may have something to do with it. Why? I have no clue but just a thought.

I do not check my pH. I just use AG nutes. Change water out once a month. For herbs I do not use the 8ml but 6 tops.
