well me being over paranoid, I would spray every week or every other week till harvest if it continued, but even on the site it doesnt say to reapply after the 2nd.
since its a designed for flower foliar it should be low risk of mold.
To use Gold Range REVERSE, simply follow these easy guidelines!
As a preventative aid, spray your plants the first time as required (usually approx 7 days into flower cycle) and once again 10 days later OR can be used at the first sight of trouble by spraying with Gold Range REVERSE immediately and once again 10 days later.
DO NOT DILUTE WITH WATER - Pour the amount of Gold Range REVERSE you need into a spray bottle. Typically 500 ml / ½ quart is enough for one application for the average sized garden.
* Important * Add Gold Range SATURATOR to undiluted Gold Range REVERSE at the rate of 10 ml / 2 teaspoons per litre / quart only! A 500 ml / ½ quart spray bottle will require 5 ml / 1 teaspoon of Gold Range SATURATOR and a 250 ml / 8 oz spray bottle will require only 2.5 ml / ½ teaspoon of Gold Range SATURATOR.
Gently shake the spray bottle with the solution to make sure it is well mixed.
* Important * - you must spray the solution within 15 minutes of adding Gold Range SATURATOR!
Make sure your lights are a minimum of 24 inches from the tops of your plants then spray your plants until the leaves are evenly coated with the spray solution and a small runoff occurs. MAKE SURE YOU AVOID SPRAYING THE GLOBES / BULBS. You only need to spray the top surface of the leaf because Gold Range SATURATOR will deliver absolutely everything inside the leaf using the top surface only. If you needed to raise your lights to spray, you may lower them back down after 30 minutes, as all the solution will be absorbed into the leaf within this time.
