Re: Lighting Schedule w/ EI? Longer/Shorter? @ 3.9wpg
10hrs is fine also, I run mine 12hrs most times.
TE=Trace Elements
That dosing schedule should get you right as rain. once you get going good with it, then you can see how things grow, and work out you're own plan...which will not be to far off from what it is now, adjustments may need to be made for whatever reason's.
I use smaller bottles, 250ml to be exact+1Tblsp, so ya 2Tblsp to 500ml.
Dose half one week then full the next, see what works good for you, how the plants respond etc...just make sure you have enough of all the needed nutrients in the water during light cycle. :gw
