I have been gardening vegetables for years. Just started growing pot last year. I try to keep it organic. I mix my own potting soil. Cow manure, goat manure, chicken manure, green sand, perlite, peat moss, garden soil and suffer. This works well for spouting my vegetables, and I have been using the mix for my reefer. So far I have had 100% germination with 26 marijuana plants. I did lose one due to transplant shock, I assume, because I dropped it while turning it over into the new pot. Last year I grow my marijuana plants in the garden mixed in with the tomato plants. I had one over seven foot tall. I cut a foot off the top twice because I was paranoid. This winter I move my marijuana inside.
The problem is I have had an infestation of spider mites, got rid of them by washing down the plants with dawn.
Now I have a new seedling that had signs of leaf miner on one leaf. I removed the leaf and flush it. I have not seen any of the mature insects. I did not have these problems with the plants I grew outside.
I am wondering if the soil I add to the mix is where the contaminations of insects are coming from. When I mix up my potting soil I do it outside on plywood. I leave the pile setting there for months at a time using as needed.
Is there something I need to do different?
