Harvest window

Looking at your pics again they look like they mite have got a little wind burned more than any real issue but the small pots and living soil just ask for issues. The plants look really good. Did they ever get a little dry and to much air on them.
I mean I’ve only got four Little fans running but I let the soil go dry on few occasions like really dry so that might be an issue

Yeah more than likely the plant will dry from the outside inward which would be the leaf tips first I bet that’s your issue but I would keep your feed schedule the same until harvest maybe the last water no food but don’t flush the soil.

I just used canna bio terra plus soil mix and I didn’t add anything, it was going great they looked really healthy till early/mid of flower. That when the issues have started and I removed damaged foil after flush, I started feeding them again but it seems like this issue is still ongoing and I can’t figure out how to fix it.
To me, that plant looks overfed with all those burned tips curling up.

Did you start using the canna bio nutes from the beginning? Or did you wait a few weeks to start applying them? According to their website, that soil is supposed to have some nutrients already in it, so if you were adding liquid fertilizer from the beginning then it's probably overfed by now...

I feel like this is a pretty common thing I see on here - growers start in soil that is supposed to feed the plant for "x" number of weeks, then they're supposed to switch to that brand's liquid nutrient line after the soil's nutrition is depleted. Usually it's Fox Farm, but the Canna Bio stuff looks like the same idea... And everyone has trouble their first couple tries with it, usually due to overfeeding.

To me, that whole concept seems pretty fraught - it's really hard to know when the base soil has actually been depleted to the point where you need to start adding liquid fertilizer, and when you do start, it's then hard to gauge how much to use without going overboard. There are just too many variables, it seems difficult to get right the first time unless you're a very experienced grower. It's not like feeding coco coir, which is more inert to begin with.

If it were me, and I wanted to continue with the organic/living soil route, next time I'd go with much larger containers like @Hiphophippo suggested, and top-dress with dry amendments instead, as they seem to be more forgiving. Or continue using the liquid feeds, but prepare for a learning curve...

I waited bout three weeks from seedling then gradually I have been adding some nutes. I added bit of cal mag on the beginning of the flowering which wasn’t a good idea as CalMag agent is chemical so that’s that. The past three weeks I gave them just canna bio booster as it says on their website that last two weeks only booster should be added. What would u suggest then? Should I do as @Hiphophippo mentioned so carry on feeding perhaps light dosage till the end?

I dunno if I really have a suggestion, since I have no experience using liquid nutes in living soil, except the occasional fish hydrolysate to correct deficiencies. But you should be good using a very light feed at this point.

And yeah Cal-Mag is another thing I don't get. I wouldn't worry about it not being technically "organic," but if you look at Mulder's chart, calcium is antagonistic to more nutrients than almost anything else, yet it's marketed as though you can just add it to your water anytime with no issues...

That strain is notorious for long flowering. I would give it ewc, epsom salt and teas til the end. Dont flush. Flushing it is a stress. U might've actually gave yourself more flowering time as plant recovers. Plus living soil gets better once re-used so why flush all the gd stuff out.

it’s been 12 weeks now so I don’t know It doesn’t look like much is changing with the trichomes etc. I don’t want to wait too long, it’s already been 3-4 weeks longer than recommended on the website which was 8-9 weeks (yes I know they usually say that based on perfect conditions) but 12 weeks it’s quite significant time. I think I’ll chop them on Saturday. I’ll try to post some more pics tomorrow morning.

There is one more thing I’m wondering about, about 4 weeks ago I reduced the lights from 12/12 to 10/14 I’m not sure if that was a good idea, maybe I should’ve kept it 12/12 till the end? If so can I dim them back to 12/12 at this point ?

Don’t make any more changes, especially do not go to longer lights on. Adjust after harvest.

right, do you think I fucked it up decreasing them 2 weeks ago? I f*** read on multiple forums that it actually speeds up the process. I had them on 12/12 until two weeks ago so most of my flowering was on 12/12 they’ve only been on 10/14 for nearly 3 weeks and I’m almost there so I’m hoping I didn’t fuck them up too much because of that. Next grow I’ll run them 12/12 till the end
