Mmm bud pron. The flash vs. the 1000w on the plants looks so cool. How's the technical stuff going? Haven't heard much about that and my noob ignorance is hungry for it. When are you supposed to apply Serenade? Is it a preventative measure as well as a cure?
I started a thread concerning the setup for my hypothetical future cab hydro, could you gimme your two cents?

Thanks man, rock on.

Sorry about that.
Data:
As has been through the entire grow, the plants are still dictating the ph, not me. After a water change on fresh nutes, they go like this: Ph rises for the first two days. Stabilizes on the third day and remains stable for the next few days and finally starts dropping again towards the end of the week. Next week after water change, same thing. Like clockwork. There's a lot of talk out there about ph drift being cause for alarm... but not so fast. I'm too experienced to think that my robust disease-free system could all of a sudden get bad microbes or some such thing. I believe, in my case, that this ph drift is due to the dynamic manner in which these plants react to this particular nutrient type in this particular ro water of mine. And I think I'm right. The plants have shown nothing but robust health throughout, so despite what some of the other posters here assert, I knew I never had what they said I had. Ph ranges from 5.2 low, 5.6-5.7mid, 5.8-6.0 high.
My ppm is now in the high 600's and drifting down to the 660's as we speak. I periodically refresh with equal parts base bloom A and B and Kushie Kush and Calmag.
My air temps are very low. The highest, hottest point is right around median 78f I would say.
I'll be decreasing the ppm in the following weeks, cutting the Kushie Kush at the appropriate time, and running nothing but final phase in the last week.
Did I miss anything? Oh yeah, fluid temp is at 68f.
edit:
Oh yeah, it's def good to use serenade as a preventative even before you see a problem.
