Chelated Iron Dosing - Is there such a thing as a preventive dosing?

Is there a specific dosing of chelated iron that one can add to his system as a preventive dosing!

I know that when you see yellow leaf appearing it is normally time to add chelated iron. This said, I would like to know if there a specific dose that you can add weekly, monthly to keep your AP system in a happy iron level?

Not too much, not too high... just enough to avoid a lack of iron!

Some specs:

  1. I have a chelated iron EDDHSA 6% (Fe)
  2. Using a IBC tote with 1000 liters water +/-
  3. 2 x (4x8x12inches) Deep Floating Raft 
  4. PH is at 6.8 / 7 range

Any advices would be welcome!

Crap...sorry TC. I just now saw that you asked "how often", not "how"...oops.

They took samples every 21 days...Sorry...

Heck, I've read how different types of fish will provide you with different numbers in the waste.

All interesting.  Did they say how often they were scooping the sludge out?

Vlad,

I'm not familiar with the nutrient ratios used in hydroponic solutions. Thanks for pointing out the similarities.

Thank you Terri explaining that to us. It makes so much more sense now. That's a pretty darn good fertilizer At fist glance it looks like those Ca-Mg-Fe-Zn-Cu ratios jive with some different generally accepted hydro formulas. (yeah, I know that's kind of a generic thing to say, since there are a lot of them, but Barry (1996), Jones (1997), Yuste/Constincar (1999) are a few that I'm at least a little familiar with)...Good stuff. Thanks Terri.
