1. Lowering soil PH is short span is impossible but you can reduce gradually by using Phosphoric Acid and Sulphuric Acid. 2. For controlling Aphids and Spider Mites click on above mentioned links. 3. During initial growth stages use 19:19:19 & 13:40:13 alternately.

Dear, using acids is not the solution to low soil pH it's after shocks are more undesired than benefits
