Please help me save my babies!! Underfed / Overfed / waterlogged. Coco LED Canna

You guys rock! Thank you so much for hanging out in this desperate time of mine...

(I'm going to cross-post again to my main thread, it will be the last time, so anyone following gets all the info.)

So what did I do today? 6 hours of intense labor.

- Calibrated pH/EC meters
- Cleaned out the res, filled it up. pH = 8.1 / EC = 0.335
- Measured how much pH (-) I needed to hit 5.8. Exactly 2ml/30L rounds to 5.5, EC the same (actually lowered to 0.315, but I guess chloride evaporates etc)
- Started flushing the medium, a little hard at first, then gently
- I let the airpots drain until slow drip. Put a tray beneath and went to roll a joint. Fired it up, chilled for 10m, go back and enough slow run-off water is collected to take a reading. pH 6.3 / EC 0.6
- I repeat the process 5x, with pH 5.5 flush water, run-off = 6.3 / 6.2 / 6.1 / 6.1 / 5.9 - > So thats 150L flush water, 30L per plant, 5 joints and calibration check here and there.
- So now that I am in the ballpark I prepped a last "flush", including a light feed. I could not let go of the feeling it is not nute burn. So I did a 1/2 strength dose from suggested Normal feeding by Canna. This rendered an even lesser feed than their recommended Light - here is the formulation



Now, I did do full dose Cannazyme and Rhizo. These two should never be a problem and in fact, quite beneficial in a situation like this. Cannazyme adds 0.1 EC, Rhizo 0.05.
I was quite surprised on how much 50% dose Canna A made the EC rise... about 0.5 !! Canna B at 50% rises another EC 0.2

So basically, I did an EC feed of 0.68 over base water. Slowly, circularly and steady until I heard run-off drippling. Let it sit a bit in the tub, then back into the tent.

- 15 minutes and a joint later, checked calibration (ok) and go read the run-off of the various trays... very surprising again. pH 5.8-5.9 and EC's between 0.4 and 0.6 - does this sound ok?
- I also raised the LED lights to about 70cm

So here are my conclusions;

- while Canna certainly does make top quality nutes and mediums, you have to take what they say with a huge grain of saturated salt.
I cannot find exactly where, but I know I saw/read that they advertise their Coco Pro+ as the most hassle free, ready to go, perfectly buffered etc.
I cannot imagine what the pH level was out of the bag. Shouldn't it be very close to 5.8? At the rate I fed previously and flushed, it would be above pH 7 - 7.5

For the sake of my sanity I hope so. If this reasoning is correct, do you think this could have been the problem?
 
I was seeing your point and thought we where having a grown up discussion with valid points here
I did not make any personal comments
Theres a reason why companies make hard water and coir specific nutes we can only work with what the op has
Don't go on about blanket comments when you come out with statements like this
"1.6 no matter what you background EC may be is WAY too high."
I was quoting your dwc grow with the coir manure mix and considering you think coir has enough nutrients for early life your way off target

Yeah, I feel ya. That lawnmower is Ridiculous. LMAO! Just to see a firkin lawnmower take off from the ground will break the tension in any situation I guess. How can you not laugh at that? Lmao.

I would shit if I saw that in real life.
