Foliar Feeding Q's

I just foliar fed my plants with a diluted solution of epsom salts and ferts, how long will it take for the ferts to be absorbed into the plant, and how often should i feed? thx in advance

They'll get absorbed pretty much right away (someone correct me if I'm wrong) but definately you'll see a perk by the end of the day. don't always give it ferts when you foliar feed though. Do some plain old water maybe every 3rd time to wash off the salts that'll build up on the leaves. And don't ever do it when you are flowering! bud rot is a BITCH!
