Noticed spider mites in the soil on my first day of switching the light schedule to 12/12 for flowering. I sprayed the entire plant with Neem oil at the very end of the light cycle for the day. I came back a little while later and misted the leaves with water to try to prevent burning. Next day the lights turned on I noticed the bud site leaves were curling down and noticeably a light shade of green. The following day I noticed browning of the tips of the leaves and noticeable brown spots on A couple of the fan leaves. I am very light on the nutes usually fish emulsion. Temperature ranges from 78 to 82. What do I do? Is this neem oil burn or a deficiency of some sort. PLEASE HELP!!!!
