Multiple problems?

Everything was peachy until this week. I have some strange shit I have never seen before. First it seems that random blades on some leaves just die. The next day that entire leaf will be black and dead. Now I am getting brown spots on the leaves of one of my plants.

Strain: SLH
Medium: Fox farm Up Country(commercial)
Nutrients: Canna Flores - Canna Boost
PH: 6.2 with a meter
Temp: 85°
Tent
Hlg 550 light


I can’t take them out and flush the pots because of the scrog. If I really need to do that I will cut the strings and pull them out.

The wrinkling of the leaves like that would be from the plant not getting enough phosphorus, i think the pic with all the leaves in them shows one on the top left part that appears bluish/green, which is also an indication of low phosphorus levels. It may just be starting, seems you're hitting mid flower, the plants looks good from the distant shot, so it may just be beginning. The dots on the leaves can be from a lack of calcium, or too much manganese.

Over fert. Don't give any more food. It looks like the soil comes from the factory with nutrients (read the packaging to be sure). If so, you don't have to give the Canna if plants are in a large enough container to last the entire grow period. Also, 85F is rather warm for an indoor grow. Is a fan moving air to help them stay cooler? The dark green leaves you have there is classic over fert condition. If you're using a soil with nutrients and giving another fert on top of it, it's very unlikely to missing anything like phosphorus. Exactly which Upcountry soil are you using? Looks like there's more than one. What does the package say about ferts in the soil?

Well the nursery is closed and I don’t have the bag anymore. It was a black and white bag so I assume it is “cream of the crop”. I can’t seem to find info on its contents. I guess it is not supposed to be for sale. It’s not even listed on the FF website.

I will just use water for a week and see what is up.

I do have a small fan below the canopy and a 4” exhaust/filter combo above.

Which nutrient specifically is he over feeding? Curious what excess nutrient causes the leaves to contort and curl in that manner. Most soils that do come with some fertilizer are not enough for an entire grow! Most certainly not through mid flower of a photoperiod cannabis plant!

Thank you for your help. I had an extra long vege cycle until the net filled. They have been in the same medium since May. I did not fertilize in vege. Switched to flower Aug 10th.

Nutrients in soil depend on how much is installed at the factory, and how much the grower uses in relation to the grow period, i.e., what size of container. Fill a large container with FFOF and it might be enough to last the entire grow period.
It's impossible to say how the nutrients are in excess unless that info comes from the factory, however, I see that the Upcountry soil is not intended for sale to a customer. It's intended "for commercial use only" according to the small bit of info I found on the web. That's why it's not for sale like FFOF. But since it's a foxfarm product I can only guess that it's structured like Ocean Forest. To add more fert might be a mistake. And Blitz, you should know better. Which nutrient causes the leaves to green up the most? Know that element and you have your answer.

lol..leaves don't appear overly green, one appears bluish. If it was too much nitrogen, that would be evident, if it was too much magnesium, again, it would be evident. Those are the two elements to cause 'overly' green looking leaves. I was asking what excess nute would make his leaves get all contorted and wrinkled like in the pics with all the leaves. You said it was over fert, i was just curious which element in excess causes the leaves to contort and curl like the fingers on his leaves are doing. A lack of phosphorus would cause that, you said it's not that, it's too much food, i asked which food specifically is too much?

I never said over fert causes leaves to wrinkle. Here's what I wrote: "The dark green leaves you have there is classic over fert condition."
Those leaves appear dark green, too much so. Please "don't put words in my mouth." Go back and read it again if you must. I never made comment on the shape of the leaves, wrinkled or not.
Upcountry soil, Canna nutes, and being pH to 6.2. I think this is over fert with forcing pH to remain too low when the nutes are fed to the soil. Over fert and low pH. Stop the feeding, just water when dry for a while, don't pH anything anymore, and see what happens. That's what I think. What Blitz asked me was "Which nutrient specifically is he over feeding?" Blitz did not ask about which nutrient causes curling. Blitz made that as a statement, not a question. In posing the question about over feeding this way I assumed Blitz was asking about the dark green color since the question did not include the leaf curl.

Greetings Fellow Growers,
First timer here and I have 2 plants I could really use some assistance/guidance on my next step.

My first plant I put in vegg. on late Tuesday night/early Wednesday Morning. I transplanted it yesterday to its final medium as well (these problems were pre occurring a few days before hand). After doing a bit of research and comparing, I thought it might be due to low N, so I applied a little bit of blood mane on the top that was also a few days ago. Looked okay for few day, but now I’m seeing maybe my soil pH is off (water 7.2, and I also add a light bit of that soil that is woody, I read it helps lower the pH) then some of leafs have tiny bit of yellowing around edges, possibly bug bites was another option I thought. Didn’t want to add to much of anything Causing the plant more stress. Thanks for your time in advance ( if you have any questions let me know I’ll answer them the best I can )549315E6-975E-475A-85B8-FFDC20A74394.jpegA9A7ED06-A4CD-4ABD-8A7F-488B86B5DEDA.jpeg 1950DF40-D240-455B-B6AC-D7A5AFCC0300.jpeg

bluedream, blood and bone meal must be put in the soil, not on top and take months to break down to a molecular level that plants can absorb. Please start your own thread next time.
Canna may say to use 6.2, but that probably only applies if you're using soil or other grow style like hydro or anything else that doesn't have fert in it already. It looks like you're using a soil that probably has fert in it which is why I compared it with FFOF. If you increase your nutrients, you have just lowered your pH some (unless it's a nutrient that doesn't have an effect on pH, which is kind of unlikely). There's things about nutrients that the companies don't tell us. You have to learn on your own.

Gimme about hr I’ll make new thread. I mixed all my stuff, bought all separately. Little caught up atm. I’ll post more pics shortly with update. I am so sorry that I imposed, leoshitz. Thought I was asking correctly, best wishes with your grow, and thanks pollishpollack, appreciatethe time

LOL...dude, you make no sense whatsoever! You said overfert, and it has nothing to do with phosphorus lacking, so i asked you, not about the greeness, which its not 'overly green' lol...i asked about the contorted black fingers on the leaves, what over fertilized element causes that? you cant answer, because its not over fertilized lol. Also, now you mention ph? You just posted two long posts in another thread to me that ph is not important at all and you don't understand why people bother checking it lol. "If pHing were necessary, there would be instructions on the container to pH to a particular level or number." Now here you are talking about ph'ing and how it may be affecting this grower? lol..oh man, im done with you dude, you are all over the place making shit up as you go lol..good luck, happy growing!

It's the nutrient content that drive the pH value, Blitz. Yes, please stop responding. I think that would be great. You're insane.

I beleive overfeeding is the cause of most "deficiencies".

Once I started feeding crazy light i have had no deficiencies. Once in a while a girl that looks hungry and you give her a bit more next time and she responds in no time, no drama.

This is simple plant to grow, we overcomplicate it to make ourselves feel more useful than we are in tne garden
