yea get the penetrator/saturator if you can afford it, makes a real difference and it can be used with any foliar application. Their liquid light spray is amazing. Lasts forever too.
Sorry I was in a hurry earlier. Here is a bit more info.
Reverse can be used as a prevenative or at the first sign of male flowers. It has a chemical smell similar to someone getting a perm. I was nervous spraying it on my girls at first but they actually seemed to like it. I was pulling 3-4 balls of my plants everyday till the spray arrived. I sprayed the plants and the male flowers stopped immediately. I sprayed them 10 days later as directed and in the end, off the mother and all the clones, we pulled close to 22 OZ and only found 2 seeds.
Reverse works best on female plants that have hermied from stress. If you have a full blown hermie throwing balls out everywhere, it's probably still best to just toss it. Reverse will not force a true hermaphrodite to become female.
