Started my cilantro indoors weeks ago and was going well, but lately the leaves are getting pale. Underneath I found these evenly spread out tiny black dots. They seem like a growth that comes from the leaf tissue. They are too uniformly spread out to be bugs. I know they aren't spider mites. Anyone seen this?

Nasty looking, mine is outdoors, has a deep tap root, the black spots aren't anything I have seen before

Looks like eggs, maybe? I don't know what they are and I'm not sure about cilantro, but black swallow tail butterfly caterpillars LOVE parsley.. before you try to get rid of them I'd put those leaves under a cover and watch it for 7-10 days, see what happens.

As for the white spots, yellow leaves, probably weather damage. Have you had any light frost since this went outside? Cilantro likes cool weather, but can't take frost.

Sorry, they are 1000% not covered in butterfly eggs after living their entire 3 month life inside my house under grow lights. And it wasn't weather- again, inside.
But thanks for reminding me to plant more seed today.

I guess not, lol! Sorry about that,
I saw that you grew them indoors under growlights, but the picture is on an exterior deck.. I thought you had moved them out for Spring, which would have explained both eggs and weather damage. Now I am at a complete loss.

I am still sure those black spots arent fungus.

Sally, bug scat can do that/look like that, and you do have something making those light colored spots,

Pale leaves can be from insufficient light, adjustment to new conditions or nutrient deficiency.. which is least likely of the three ....typically Mg or nitrogen but there is a lot of drama surrounding both of those ideas, especially from inexperienced land gardeners with rich soil who water regularly with hard water.. Blinking YMMV

I am probably too cautious with fertilizer on my seedlings, .

I dont think you can be too cautious... not with a potting soil. More restraint is better.

Even though I am VERY familiar with spider mites, and didn't think these were, I now think they are a mite. I can see webbing.
Maybe it was lucky, in that my Brug cuttings never got mites this winter. Maybe the cilantro sacrificed itself. Shrug!

do you think they could have been inside all winter and not show up?

Spider mites inside for winter is a given for me. Colocasia and Alocasia had some. Just cut off leaves and let them be mostly dormant. . Brugs had some but somehow I got over those..

Have you ever tried a systemic pesticide? I always bring my plants out for the summer. I had two really bad winters in a row with both spider mites and afids. Everyone went out for the summer with a neem oil spray. The next fall I treated every pot with a systemic pesticide and, knock wood, I've never treated again and I've been pest free for at least 5 years.

This is a current year seedling. If it came from inside, this is the last place it should show up.

You guys up there in the city have totally different weather than I, I did change my cilantro and am having a lot better luck with it- but GH's are too hot for us even in the bad part of winter. Now, waiting for seeds to mature. This is Coriandrum sativum var 'Confetti'...cilantro.

I saw a label "confetti cilantro" at Lowe's for the first time today.. that's really interesting.
How do you like it? Does it taste the same? How has it tolerated conditions/grown compared to traditional?

This a pathogen disease caused directly by your plants getting to much H20(water) Not that I have had much experience growing herbs hydroponically (why should I) I would say from looking at the photos that you may have a humidity problem also. Are you using fans or are the plants spaced too close together.

Regard's,
