HELP! Powdery mildew? Spider Mites?

[Vevenda]

Hi. 1st grow in 20 years. 2 weeks in veg and I have a whole host of issues. Each girl is a little special this grow. Any idea what might be on this leaf? Temp between 76-82, humidity between 25-45%, 18/6 schedule.

Looks like bugs

 

[Ponky]

Yeah. You have all the problems. You got tent? Whats going on in that setup? The "---------- looks all ------- and ---------"

 

[NorthernOrganics]

Pics of the whole plant...?

If you look on the side of the leaf in both pictures, it looks to be an aphid casing or exoskeleton....so I think you have aphids but you may want to explore it more. I cannot see too well in the picture. They leave their extoskeltons around as decoys for parasitic wasps. The wasps attack the casing and not the actual aphid.

You still may have spider mites but the treatment for both is about the same, although aphids are a bit better at hiding. How big of a plant?

I finally got a pic of the spider mite. I showed another pic to someone at a grow store and he was convinced I also have powder mildew. Weee

Have a brand new 4x4 tent with a KIND LED x2.

Is that soil? Or backyard dirt?

Indoor soil grow

Where'd the soil come from?

So you definitely have spider mites....Looks like PM as well and a few aphid casings......Plant is hurting to be honest but not down and out yet. Plant nutrition will help fight all those back. I don't know your situation and whether you want to just start over with this plant. If you want to keep it, i would defoliate any of the larger fan leaves that have mites for starters as well as pm. Leave the growing sites alone even if they have mites (you can get them later).... The purple stem is an indication to me that your pH is off but Ill wait to hear more

you can treat the plants, and the plants can recover, it may take some time.

i use white oil spray application, then use isopropyl-alcohol-water mix (1:10 ratio) spray a couple of days afterwards. they can be hard to eradicate.

also, clean your grow area. restrict movements between grow areas or sites, etc.

It is a grow mix from a local soil company

Since this is my 1st grow in 20 year I am going to use this as an educational grow; even though it might be a bit painful. I only have 1 4x4 space set up to grow that currently has 4 plants. I chatted with someone in the area that bought clones from the same facility and they too ended up with powder mildew. The 2 wedding cake had purple stems when I bought them. The ph of the soil has tested a little under 7.

I will defoliate the bigger effected fan leaves today.

In my opinion weakness to PM is genetic. And I don't finish plants with that affliction.

It can also be passed down from a mother plant if my understanding is correct. This will be a good lesson for how to deal with it when it occurs.

If the mother ever had PM kill the entire lineage. Get those weak genetics out of there.

spider mites are the most destructive pest and I have changed out whole areas when identified as they are impossible to eliminate
