Please help

Does anyone know what’s going on wit these plants I think they got aphids or spider mites but what deficiencies also

I don’t really see any signs of mites

please provide some grow info before anyone can help give you accurate advice.
They don’t look that bad to me but the stems are very dark colored and I see a small leaf on back side with something going on but can’t tell what it is.
Why do you think they have mites or aphids?
How old are the plants?
What is the medium they are in?
How often are you watering and feeding?
What is your temps?
What is your RH?
What is the light source and how far away is it?
Hopefully you can get some info with those answered

Thrips

I can't see the bugs but the purple stems looks like a magnesium def

Hard to be sure with the photos and info given. But, this damage looks like thrip damage.

It does look like some small clear looking bugs on a leaf and on the stalk up high but I can’t be certain from the pics. But what I can see does look kinda like thrips.
being In veg and thrips are pretty easy to deal with so best of luck hope ya get them turned around
