Got some organic spray for mites. Worked really well. They were gone within a few days.
What was the spray you bought, I'm always looking to try new products for mites? looks like you had a good recovery from them. Little bastards are a pain.
On a side note, now that you recovered from the mites, focus on your environment and what mites don't like when trying to survive. Mites hate high RH, water, cold, lack of light. With that being said, 55-65% RH with temps in the 70's should do the trick to keep them away. I noticed your watering every few days, what size are your pots? I grow in 10gallon bags and do a gallon of water a day, try not to let the soil get too dry. Dry soil means plant is running out of water, which is creating dry air= mite baby making environment
