Deficiency - Outdoor

[Gosurround]

Looking for a little help to figure out whats happening here. Its super silver haze strain grown outdoors in a 100 g smart pot. Plants are now 8' tall. This looks to be happening to the top of the plant or its new growth. Bottom leaves look totally normal. Soil is 50% seafood compost 50% topsoil. They've been outdoors for 1 month now and no other nutrients have been added at this point, ph is 6.4. Any help would be greatly appreciated.

Hello Gosurround , Man what some nice plants, Looks like russet mites to me, and if it is, I sure hope that you get rid of them, plenty of different stuff that you can use, to take care of them.
And good luck.

Yes looks like bugs. Get rid of them quick. Neem oil. Sm90. If you dont care about organic look into a loa dose of pyrethrin. It is from plants but cant call of organic now.

I know mites can be hard to see but I don’t see anything on the underside of the leaves. The plants were started indoors for a month and then hardened off over several days before transplanting outside and have now been outdoors for a month. The last two weeks have been very hot and sunny, hotter than prior or even this week. I’m wondering if this could be a sun stress from not hardening the plants off enough prior to transplanting. Anyone come across an issue like this? I did a NPK test and all results are showing sufficient to adequate. Would it be worth treating for mites anyway even if not totally sure thats what it is?

It could be the change in conditions, but it sure looks like mites to me, and that's about all i ever grow is outdoors crops, or use to anyway.
Yes, I would treat them anyway, just to be safe, and good luck, if it is mites, you are going to have to treat them more than once,
or they will be right back.
