outdoor bug problem

hello everyone. this is not my first grow. but it is the first time i am growing outside. inside i never had a bug problem. but now that i am outside its a problem. i have read every post i can find and still no luck. my problem is this. i have 14 plants spread out on my 45 acres. they are in recycling containers with a mix of pro mix and ocean forest soil. they are growing great but some of the leaves have groups of white spots they are very small and very close together. i looked on the bottom of all the leaves and dont see much. although i did find a few orange or amber colored things that looked like spider mites but im not sure. i think spider mites are black or red. i spray these plants with neem oil both the top and bottom of the leaves every 5 days. i have encluded pictues so anyone who has an input please let me know.. also i have seen a few things that look like white flies but i only seen about 4 or 5 or so on all my plants. and not all the plants have this problem..thanks again

Looks like spider mites to me.
They are bad so get on em quick.
I use seven spray to kill bugs during veg,
flowering im using tobacco juice lightly as a deterent.

Sounds like mites, and there are some mites that are orange too. Pic 4 kind of looks like you had caterpillars eating the leaves. Though there are a number of bugs in the great outdoors that might consider your plants a free meal. Fortunately mother nature and modern science both have ways to remedy the situation. Good luck to you. Cheers!

okay i will go with the fact that they are mites. what do you think about switching the spray from neem to sevens and switching week to week just so they dont get use to one pestacide. also where can get sevens?

Switching may work, though if you find something that kills them it'll probably work most of the time. Mites are really invasive, and you have to be persistent in eliminating them. There are a ton of pesticides on the market for that application-- that are safe for the plant. A natural way is using lady bugs-- but if yours are spread out that might be more difficult. Are you talking about sevin or seven dust? If so, I don't know if you need to use something that strong-- it kills EVERYTHING. It's a carbaryl, and if you handle it enough without gloves it can make you sick too, so handle with care. It'll take care of just about any bug on your plants, but make sure you flush really well before you harvest. I think smoking even traces of that stuff would be more than unpleasant.
