Hello guys!! I just got this plant about a month ago. At first it had a few red dots but now it’s turning yellow and brown. Any suggestions on what is causing this?

JosieIf it’s not an older leaf then I would guess possible overwatering. The spots might’ve been edema from too much water and now it’s getting root rot? If you’ve repotted it recently it could also be repot shock.

Hey. This is a picture of it when I first got it like 3 weeks ago. In the picture there is red dots on the leaves. I repotted it about 2 weeks ago to PON.

Thank you Josie! I just checked the plant and it’s definitely getting root rot!

SunnyI agree with Josie that it looks like too much water especially with the yellow parts that turn brown. Don’t water on a schedule without verifying the plant actually needs water by checking the soil. The top 2 inches of soil should be dry before watering. Place it in bright indirect light. Yellowing can occur from too low light. Lack of sufficient fertilizer cause it to yellow and go pale.

Although if it’s in Pon now I think you’re supposed to keep water on it but I’m not familiar with that type of planting

KDepending on the previous potting medium, plants that are switched to semi-hydro like pon may go through a period where some of their old roots adapt to the new conditions and others will slough off to make room/free up resources to produce new roots. It’s important to distinguish dead roots from root rot because they have different causes and approaches. Root rot is caused by pathogenic bacteria and fungi, generally in an anaerobic environment. If you cleaned the roots well and they were healthy when you converted to pon then this is less likely what’s going on. If the roots still had a good amount of soil on them or had pre-existing rot then this is more likely.

The alternative is that they may be dying off appropriately with the change of environment, which will cause stress to the plant but isn’t going to kill it. In this case, you don’t want to go in and mess with the roots, as this will just stress it more. You instead want to provide appropriate watering and flush the plant every 1-2 weeks to help move the dying roots out of the pot. You can also give it supplements like thiamine with watering, which many feel helps with the transition. You may know all of this if you’re experienced with semi-hydro but just wanted to include that detail that goes beyond what you usually see in non-hydroponic repots

I don’t have a lot of great examples at the moment but you may be able to see some of what I mean on these roots in leca. Right in the middle, going horizontally, there’s a root that’s brown, doesn’t have branches or hairs coming off, and clearly doesn’t have the same turgor as the other roots. That root is dead/dying but not rotting, so it’s not a problem and not an indication I need to treat the roots. You’ll get a lot more of these earlier in the transition (this one is a few months in) and then once the plant is fully adapted you’ll see it a lot less. Some signs that it’s not rotted include smell, the fact that it clearly has lots of oxygen around it, and the fact that it’s not “spreading” to the other roots that cross its path. These roots can range from a very translucent white all the way to brown but generally aren’t black
