Plant dying? Can’t figure out what’s the issue

Hi,

I’ve been posting recently about the problem I’ve got and it seems like it keeps getting worse, my plants look miserable af. I’ve got two autos in canna terra plus soil, I’m in the 9th week now counting from seedling. I’ve had some issues going on for about three weeks. Two weeks ago I gave them very little dosage of canna flo, before that I hadn’t used any nutes. I’ve been using bottled water, I was stupid enough not to check ph of that water as it said on the label 6.2 however last time I decided to check it and it was around 7.0 so probably messed ph of the soil. I thought that I had some Cal-Mag deficiency so I gave a bit of a cal mag to one plant and I flushed the other with ph adjusted water (ph 6.5) I just wanted to see which would work but none did. I think they getting worse everyday and I don’t know how to fix it nor what the problem might be. I’d really appreciate your help. Thanks.

all the bottled water I’ve used is pretty much ro. Always had to add some calmag. Like 150 ppm. It is what it is with this one. On to the next. I would use some calmag. I don’t water till runoff either. Ph of 7.0 with nothing in it should t really affect your ph. Can’t really even check ph if there isn’t something in the water to buffer it. If you feed bottled bites and get your ppm up then you can tell what it’s going to be. Just my experiences anyways. Take it for what it’s worth. If I add 2.5 ml calmag and 1.5 ml of liquid karma my water comes out at 6.5 and 190 ppm.

I hit one of them with Cal-Mag and some nutes yesterday and it looks miles better today so seems to work. I’ll do the same with the other one today. Leaves are fucked already so I don’t expect some high quality stuff out of them two but I’d just ride it out hope I’d get some decent stuff.

Bottled water ?

If you ran TAP - most of your calcium / magnesium would be covered. No need for Evian / Fiji water.
Its a plant. NO need for special things.

Your nutes would also be a source of calcium and magnesium. Problems seem to be PH related but apparently you have been light in feeding. That medium only comes with a light “ precharge “ of nutrients and requires a regular feed to maintain.
Apparently it is mostly peat - wood products / some compost / perlite and lime. The lime buffering may be waning by now .

Flushing probably exasperated issues since that alone leaches medium even more.

Even if you course correct - damaged leaves will not recover.
