I have a couple questions regarding foliar feeding.  I am currently feeding with a mix of Optic Foliar’s Transport, Azamax and Canna Boost once every 3 days.  I filled up a 1 gallon sprayer  about halfway a couple weeks ago and because my plants are only in week 4of veg it doesn’t take much to spray them all down.  Anyway, my first question is, can a foliar mix sit for too long and become ineffective?  And my second question is can I feed more frequently?  Would it be bad to foliar feed every other day or even every day?  Thanks in advance DGC!
