No - there "purple Maxx can be used as a foliage spray - Extreme's Gardening - Cal-Nag foliage feed is great stuff. Like to foliage feed at least twice in veg (week 4 & 6) maybe one could foliage feed in pre-flower stage but spraying the buds; just don't like to do that. Have used at recommended amounts with no adverse effects - did notice increased trichome development no matter what strain Humbolt County's Own = great stuffthis line of nutrients can be tricky. definitely, do your homework using this line.very strong.
I am wondering has anyone used this as a foiler spray?
