First time indoor growing is this spider mites?

First indoor grow day 38 soil is fox farms ocean forest top dressed at day 30 with Dr. Earth all purpose organic. Growing on the tray2grow system from autopot water ph was 6.7 just adjusted it to 6 today. Using diatamatious earth at week 3 as a pest preventative. Just noticed a few leaves yellowing as well as rust looking spots on lower leaves this morning when I hit week 6. Was told this could be spider mites and I'm devastated and not sure what to do.

You probably need a magnifier to be able to see them but it does seem to be mites. The picture with the underside of the leaf looks like it's full of eggs.

What are you thinking of using to remove them? I like to use a product called Azamax for mites.

Is azamax safe to use on indoor plants? I had some diatomaceous earth so I coated the bottom of the leaves using a makeup brush and put a good layer on the top soil for now.

Spider mites leave tiny white spots on the leaves, and I don't see any. They live on the underside of the leaves. I need magnification to see them, so I can't tell if they're mites from the pictures. To me, it looks like a nutrient problem--possibly calcium. The yellowing pattern resembles nitrogen deficiency. I wouldn't rule out over watering, as well. I'm also wondering about the pH. Organic nutrients usually don't require pH adjustment.

Yeah it's safe, I've only used it as a soil drench though. Wondering how @PooToe is using it?

My first thought as well... now if he's got a gang of calcium already in the soil then maybe it's a lockout? just read the OP more thoroughly.. seems like it's been 8 days since he top dressed, the amendments need to be broken down into a usable nutrient for the plant. That could take 14 days, and that's if there's a healthy thriving soil full of biodiversity, bacteria, fungi, protozoa, etc. Easily done by adding some compost and/or earthworm castings. Lot to take in if your not accustomed to the garden. The quick fix until all that gets settled is daily foliar sprays. And quick means about two weeks the same unfortunately bit it'll work. Get some compost (BAS has some real good stuff) in there asap. Good luck man.

Thank you so much man I really appreciate it. I'm glad that it's hopefully not mites I've heard terrible things. I did buy some boogie brew black fly larvae frass when I first bought my nutrients. Do you think that would work or should I buy some compost and/or worm castings? Thank you again!

I just adjusted my ph to 5.5 in my reservoir I'm using a tray2grow system and the collector reads almost 6ph exactly. It was pretty high Saturday like 6.8. I just got my established plants moved over to it. Those are the ones that started to show those signs on some leaves so I was confused and concerned. They've been on the system about 9 days now. Could the high ph cause a lockout possibly? I haven't top watered at all just letting it ride on the system top watered when I applied the Dr earth top dress waited a few days and moved them to the system.

Compost/Worm castings have all the magic to make everything you drop in the soil work. I have to point out that the pH of organic soil runs a little higher than what bottle fed nutrients use. Bottled fed nutrients work best between 5.5-6.5 abouts.. organic soil works its magic between 6-7 pH.

Not seeing the webs or damage associated with spider mites. Slightly calcium deficiency definitely present though.

I foliar apply for mites and other bugs.

My understanding is the stuff is a concentrated active ingredient of neem oil. It freakn works. It's my go too when all else fails. I was initially skeptical to the product and scoffed at the guy at the hydro store for trying to sell it to me, didn't faze him, I'm small beans compared to his usual costumers...lol. But we had an unusual pattern of weather last year that brought in these gnats like crazy. I had no choice almost. The Azamax did the job. What ratio do you use for foliar sprays?
Edit: looked it up, 1oz to gallon.

 

[PooToe]

Yup! I use one of those mini foggers. I find it gets into everywhere I want it to go.

I agree. It is very effective at controlling bugs and is relatively safe to use. It's OMRI rated whatever that means.

I've used it in flower with excellent results. If you try and use regular Neem in flower the flowers get gummy sometimes. I know most people say you shouldn't spray anything on your flowers but when you have webs on your flowers you have no other choice if you want to save them. The bottle says it breaks down within 10 days but I would probably stop using it at least a few weeks prior to harvest. It is the only pesticide that I would use in flower that I have found to be fairly safe. Granted, I don't like using anything but.....
