Help first time grower

This is my first grow and it has been nothing but issues. The clones I started with came to me with mites. Have been battling them all grow. I am 3 weeks on flower and I used a homemade spider mite solution of 1 ounce rosemary oil 1 ounce peppermint oil 2 ounces neem oil and 1 ounce of dawn dish soap mixed in a gallon of water. So i sprayed the plants before lights out and today they are all wilted. Have i ruined my harvest? Is there anything i can do?

Now this is just my experience and I have no 'professional' information about it so take it a that...lol
Anything I sprayed on my plants when they were in flower ended up killing all my flowers and most of the mites, but they kept coming back...little buggers hide really well...lol
I finally took clones...isolated them from the grow room...re-vegged and treated frequently and cleaned the grow room over and over.
I have not seen any mites for the past few months and hope to never see one again.
Good luck and happy growin'

Virtually impossible to really rid the space while growing. It may be extreme, but you must sanitize for approximately two weeks. Trying to battle the Borg whilst trying to grow is very difficult. They must be dealt with with extreme prejudice or you will be fighting them forever.
Clean with bleach or iso everyday,bug bomb the room every 4 days for two weeks. They are insidious.
Only my two cents.
Good luck.
