First Time Grower! Best Organic Nutrients??

im a first time grower an am doing my first medical grow outdoors i have 4 clones(Strawberry Cough, Platinum OG Kush, Grandaddy Purlpe, And Purple Diesel) that are about 5 weeks old in 3.7 gallon pots using fox farm ocean forerst soil. i was wondering what is the best ORGANIC nutrients to use through out the grow?? Also the best way to get rid of Spider mites with out puttin chemicals in it?? ive been spraying the lil fuckers everyday but they seem to always come back....the only nutrients im using is GENERAL ORGANICS BIO ROOT?? But what other nutrients should i use??

spider mites: look under pest control but real quick for organic...can mix up neem oil with wetting agent in water, spray tops and bottoms of leaves every couple of days for a few weeks. You can also crush up a head of garlic, add a couple of drops of dish soap (ideally something like dr bronners) and put it in water, spray the bastards. cheap, organic and readily available. You can get dr bronners at health food stores or even Target these days...over in the area where they sell loofas.

For mites I use a mix of water, a lil vegetable oil, and a lil soap. Spray the plant with this often. Sometimes I also add some neem oil which also works well straight.

The whole general organics lineup is excellent if you can get your hands on it. Blue mountain organics is also very good as well. I've used and can attest to both. You cant overlook the quality of a nice compost tea with additions such as kelp meal, alfalfa meal, molasses, fish emulsion and guanos during flowering.

For any insect problem I always either go to Azamax or a spinosad based insecticide.

Alrite thanks for the feedback I coulnt find any neem oil so I ended up getting some Stuff called ELEMENTALS INSECTICIDAL SOAP its made by a company by the name of ORTHOS I bought it at walmart it says it's for organic gardening an kills mites an other insects so hopefully it works. But ya the local hydroponics store has the whole general organics line so I mite go grab me a few stuff!! Any other suggestions??
