preface all this with the knowledge that this is in fact my first outdoor grow ever, and I have limited indoor experience...but Hey Luna and PR i have used Liquid Light with success this summer on outdoor. It noticeably strengthened the leaf structure and increased Veg phase. I am about a month into flower and used it this morning. I do half strength every 2-3 days. I used it until week six bloom on my midsummer harvest.
Just make sure you use it before the sun in high in the sky. I have used it up until about 9:30 AM when the sun is coming out from behind the trees and becoming direct. I always use penetrator as i think it does a great job of preventing the beads that cause the burn. Hope that helps a bit.

I'll be tuning in to hear the answer from WH's Guru...love ganja gurus...:thumbsup:
