I hear where you're coming from.
I'm not really giving him a total nutrient schedule, just a guide.
I don't think there is TOO much of a difference between Flood and Drain, and deep water culture as far as EC tolerance is concerned.
If anything, I would think that you could run (minutely) higher EC in Flood and Drain than DWC since the roots aren't constantly in contact with the nutrient solution.
That really hasn't been my experience with it though. I've found the EC tolerance in DWC and Flood tables to be exactly the same in my room.
I have used FloraDuo for over a year now. I used it in DWC (I started growing in DWC, still have 2 photo's in DWC) and the results as far as EC levels the plant would tolerate were the same.
Took a couple of weeks to hit 0.8 EC without wilt, or burn. Never got above 1.2 in FULL bloom.
I'm just taking a guess that people running DWC and a .8 EC with sprouts aren't using RO water.
I have 9ppm water, so ALL of my EC is nutrient. Vick plans on running RO so he's running identical nutrients with identical water.
GH nutrients pack a punch.
Better to err on the side of caution with FloraDuo
No nutrients for a week. Standard auto practice.
Unless you're running root stim. Most root stims have P in them. P helps root growth. FloraDuo B is higher in P.
Makes a good non-hormone root stim if you have nothing else and I haven't seen any harm in it.
We all know Kush knows his shit. I'm not knockin Kush at all.
Much love to Kush.
Me and Vick just have a lot of real factors in common. Same nutes, same water, hydro.
Our EC tolerances are going to be the same. Strain dependent of course.
I know absolutely for sure that running .8 -.9 EC right out the gate using GH FloraDuo in RO water will murder an auto.
gotta get some new ones .
