Can you get access to a local water test report? Could be excess N in your tap water from agricultural runoff.

I have no idea why but it stopped the problem I had, I just use the whole canna range, well A&B, Boost and P/K, with some B'Cuzz bloom stim

Tried using molasses and the Rez turned cloudy, also tried using medical grade Citric acid and got strings of slime, so I just use what they say, the coco and nutes were designed to be used together and winging it doesn't seem to work, have say getting some excellent results

As for tap water, if the nearby water mains have been worked on then it's standard practice to flush the main with a variety of chemicals any of which can kill your plants instantly ...then there's defective dosing stations and just plain stupid behaviour like the accidental dumping of aluminium sulphate in the water supply to a city in the UK

I always taste the water before adding it to the res, also smell it .... Having said that I've only had 4 instances in 25+ yrs of contamination

because canna coco nutes are formulated for tap water & have lower levels of the NCM in them.

if it were me ..... i'd invest in a good RO system & use only that . that takes out any of the variables that might change in the tap water . its worked for years for me !

Do you ever try flushing your pots with a high volume of low level nutrient solution? Have you ever tried using drip clean?
Aside from those two little nuggets I'd say go with ro water. Maybe do a side by side with some ro water and see if there is a difference.

Up here the water is very clean but with soil erosion, turbidity (large particles carried by water force, not dissolved solids) increases and you can smell the chlorine when it rains. Arbitrary turbidity caps (in other areas up to 5 NTU, here 1 NTU) mean lots of chlorine and frequent boil water advisories.

Poorly filtered well water abounds, bringing a range of issues.

Tbh it's quite likely that the treatment has changed. I'm not sure if the water source has. Tbh the water here sometimes gives me a sore throat so I won't drink it. And sometimes smells of chlorine. And I have changed grow spots over this time but the water is still provided by the same company and source. I've checked the website at their own tests of the water but they don't test for magnesium which seems odd. I rung them before and they just don't test for it. Plenty of contamination of other kinds but I'm no guru with water quality so I don't have a clue which contaminant/s would effect my nutrients.

Yes man kinda done the same. Run canna for the first few weeks and low and behold got the same shit again. Don't suppose you live in the southeast? This is where my water is sourced.

That's quite a good fix but I'm feeding a 25 litre daily so it would cost me a fortune and will need to buy 5 x 5 liter bottles a day.

Quite possible I will check the website again. this has been an issue for a long time so I doubt it's a one off contamination. Will defo read their own water analysis again. Thanks

Hello man, I appreciate the reply.. I did switch to canna for one run. That was just the Coco a&b and the boost. Same issues occurred about two weeks in so dropped it and when back to the regular feeds. Probably could have sat it out but didn't see the point since the issue was the same. That's with 2ml per litre a and then the same of the b and I think 2ml per litre off the boost too.
However this run have switched to the Coco friendly sensi bloom. Same issue. So eve Coco specific nuts don't seem to make a difference

Get a chlorine test strip. Check how many ppm's are in your tap water. If it hurts your throat it may be high? Pool test strips are fine.

Just wanted to mention Chloride toxicity. It makes plants super dark green. I have a hard time believing it's N toxicity at your ppm's. I suppose the coco could hold onto it if you overfeed N throughout veg? But unlikely. Plants use way less chloride in flower so maybe why the toxicity manifests.

How do you measure pH? How often do you calibrate?
