lime-rite

hey guys i recently awoke to curling fan leaves and came to the conclusion it was a ph problem so i went and bought lime-rite which are tiny brown pellets. Is this fast acting or will this take a long time to adjust the ph of my soil? Any suggestions?

I just bought some of this as well. Tho, mine is not pellets. It's not dust either. I'm gonna top dress (sprinkle it on top the soil) at 2 table spoons per gallon. I use 2 gal pots, so 4 total. Hope it worked out for ya. Any advice is welcome. Thanks
