First ever Grow: Gorilla Glue #4 Auto

Slowly but surely we are getting there. The buds are swelling and getting covered in more and more trichomes each time the lights come on. The mite issue seems to be kept in check: topsoil daily misting of neem oil solution plus the use of atomised cinnamon in each feeding seems to be doing the trick. No leaf or bud has seen any mites so far, fingers crossed, and 3/4 weeks away from harvest I would like to keep it that way. It may very well be the case that they are compost mites and they are only feeding on decaying matter in the soil. I have increased the feeding schedule a little: knowing the she has been particularly sensitive on ph ad feed changes, I have kept it still relatively low considering these are the second or third to last week of feeding. ppm is at 1000 or lower; I could admittedly push it to 1400ppm right with intermitted lower days at 7/850ppm, but the last thing I would like to do is to fall into another nute lockout.
