Im a new grower and I am using Oregonism right now, I've applied it three times. The first time I tried it I applied it directly to my potting whole in the soil and I think it was a little too much when it combined with the nutrients in my Fox Farms soil. So I re-transplanted into the same soil and watered for two weeks, after those two weeks I applied it to water (as advised in instructions) and watered with it and I think I saw an immediate difference in size. Since then I've used it once more but havent used it again cause I have to retransplant and I dont want to do too much.
