Yellow roots and leaves on cutting

[abeadbapda]

A while after my cuttings started to root and leaf out, they began to develop black spots and turn yellow. The roots yellowed and died back too. Then the leaves dropped off.
I'm using Coco coir.

Is this due to over watering?

Is it time to put these into a better draining soil(promix HP is on the way)?

As always, thanks in advance

How often have you been watering? Has anything else changed in the environment in terms of temp or light? Are your other cutting showing similar distress?

[abeadbapda]

I've only had to water twice so far. The Coco coir takes a long time to go completely dry.

I've switched between Southern window lighting and 6500k t8 lighting. Only switched to the lamp when I ran out of room on the window sill.

3 of my 6 rooted cuttings are already showing some degree of yellowing roots. But only one cutting has shown the leaf spots.

Some yellowing of the roots is natural especially in a clear cup? Is this cup in a window? Are the 3 cups with yellowing roots the ones in the window? I wonder if the roots aren't getting too much light

[Backyard_Fig]

I would wrap the cup in tinfoil and see if there is improvement. There is a bunch of guys and gals way smarter than me on here and I am sure they will chime in as well

Nice photo. It's probably not enough air getting to the roots. I'd up pot it. What medium is it in now?

I'm thinking block the roots from light and onlybtine I've seen yellowing roots is too much water.

Are you providing any fertilizer to the cuttings?

Along with possible increased aeration as Bob C., Harborseal mentioned lack of nutrients may be an issue. Also sunlight can "cook" the roots if the clear cups (dark potting mix) are exposed to direct sunlight. Good Luck.

if that was mine I would be potting it up in some Promix looks like plenty of roots there

Just for others viewing this post: The yellowing of roots itself shouldn't be alone be a concern if there is normal growth occuring, that is the lignification of the roots and is normal as they age. All my rooted plants were like that last year and none of them died when they got to the state you are at. Only new feeder roots will be white initially. You can up pot if you want to better draining soil.

Also - artificial light will NOT harm the roots. As pete mentioned - only direct sunlight can cause the harm, so if you have them under bulbs you are fine.

Even if you're not over-watering the pot as a whole, water will collect where the root meets the plastic. This drowns the root. The first sign of that is yellowing. At this young stage I don't believe that roots lignify. What I believe happens when the roots are up against plastic like this is that they get too little air, start to do poorly, then the water dries up and they recover and this repeats. If you look at roots this age that aren't up against plastic they' remain pure white. That's why I recommended up potting. If you can't the next best thing is to make small holes on either side of the root without touching the root itself. Make a few pairs. This will let the excess water evaporate but you'll probably have to water it more frequently. With a plant this young in soil I don't think there's a mineral deficiency yet. Nothing's impossible but it wouldn't be the first thing that springs to mind.
