Please help :) Flowering Auto showing problematic symptoms

RO water usually comes at 6,5ph which is totally fine for you, but if the bottled water youre using has minerals its probably not RO, you can check it in the label I guess. Ph of bottled water ranges from 6,5 to 7,5 depending on the method used to make it drinkable. Same happens with tap water, if you have a RO filter it will come at around 6,5 but otherwise it will be higher. Its always worth checking though, specially if you have not changed your RO filters in a while.

Also many times nutes can mess the ph of the water. Specially if you have organic nutes and they ferment but not exclusively. Some brands use fermented kelp or plant juice and their liquids have a low ph by default. And many supplements might also acidify or alkalinize your water or your soil so you gotta test it after adding the nutes to the water too.

Oh I see. Well, Palgron Alfa uses kelp, I believe. Here is another photo taken just now. What do you think?

Do you mean N (nitrogen) instead of Na (sodium)? The downward curling leaf tips indicate nitrogen toxicity (excess). The leaves also look dark green to me, which also indicates N toxicity. Stop feeding nitrogen and water with plain water. During flowering, P (phosphorous) and K (potassium) should be increased to promote bud development, but not yet.

Do you know what caused this damage?

I'm also wondering about that white spot. That could be insect damage.


Do you mean these?
View attachment 2477106
I recall seeing this on the forum, but I'm not quite remembering what caused it. IIRC, something blocked the light, preventing photosynthesis.


How are they getting natural light? Are they outside or in a window?

Lastly, I agree about adding perlite for your next grow. I also recommend using fabric pots.

Hey there! Got another photo taken just now. Please, what do you think it is?

Hmm yes I think you should check the PH before we start ruling out other stuff, also the soil is probably wet for too long. If there is N toxicity I dont see it being the major problem still. The thing is that overwatering and N toxicity can look very similar when in early stages so we cant just say "its this for sure". The yellowing and dots are for sure not N toxicity.

I would say it's over wartered

 

[Eledin]

Have you checked for bugs like @LoveGrowingIt suggested? The dots could be insect bites, or they could be caused by improper ph.

Yeah checked for bugs but there's none. Plus all the other plants are fine, even the chillies lol I've just purchased a ph detector and I'll be checking that as soon as it's delivered. Hopefully, it's that. I understand it can be fixed relatively easily. It'd be a real pity to lose the plant now that's nearing the end :(

Well the soil now is quite dry, in fact. Flushed it last Sunday, been a few warm sunny days. Some of the top, new leaves on the buds are showing symptoms of underwatering as today was sunny and warm.

Thank you. In honesty, it's come as a huge surprise to me as I've been following the same schedule as the others, keeping in mind that less is more and watering from the bottom.

What's the solution if it's over watering? I read that there's none to root rot?

 

[dropandheathersgrow]

Let the soil dry out like 3 days is say

Thank you! I checked for the at and, while it would benefit from reporting, it's not heavily root bound. Plus, the other plants have grown and flowered in the same conditions without any problems along the way. But yeah, could be genetics as these plants are from different seeds.

Cool! If you have a ph pen remember to calibrate it with a pack first, if you get the droplets its fine too its just a bit difficult to see the colors with organics, you need to put the tube against the light and check the border of the water to see the real color.
You need to meassure the ph of the water you use, tap too if you use it ocasionally, and then the water with the nutes. Let us know! I still think that soil is staying wet for too long wether the ph is okay or not, its also showing signs of overwatering or underwatering, theyre very similar but underwatering yellows your leaves faster because they also draw moisture from them, sucking the nutes in the process too.

Also the solution to ph is buying a ph down and a ph up, depending if you need one or both. Theyre very cheap because you dont need to use much. I recommend the general hydroponics ones. Avoid citric acid based ones, while citric acid can be really good for organic in small pots you can easily burn them.

Thank you! I'm waiting for the pH detector to be delivered. I'll proceed accordingly if it turns out to be a ph issue.

I though about nitrogen toxicity but more than clawing its just the tips going down which makes me think its the soil staying wet for too long instead. Good eye, didnt see that dot.

I’d second that on it being wet soil. That color isn’t bad enough for true nitrogen toxicity and the leaves usually twist vs claw when it’s bad. Also how thick are the leaves. If you got too much nitrogen but not quite hit the twisted leaves they usually get really thick

Thank you! They're not quite thick. Some of the very top leaf tips have twisted. But anyway I'll wait to check the pH/moisture as soon as I receive the soil meter, should be a couple of days. Will keep you posted

Hey there! Got another photo taken just now. Please, what do you think it is?

Can you change out that pot to a fabric or air pot?
The terra-cotta pot, a plastic, or any solid pot with a potting mix that holds a lot of water could be part of the issue after looking at the photo again this morning.
It might could stand to go to a larger pot as well. Water and the roots don’t have much place to go. Meaning fabric pots and more room the water would settle to the bottom and evaporate from the sides. This also lets the roots breath and air prunes them which will in tern mean a denser root ball.
While she will recover. This clawing could also be pre or just the very beginning of root rot. The roots can’t breath/uptake oxygen if they are standing in water. Leaves droop/show color changes.

Thank you. Ph is 7.5 so I'd rule that out as pointed out in previous comments. It is quite root bound, but it's dry. Dry as in both by the tester and by touching it (I pulled the whole block out of the pot and touched it myself). The roots are a yellowish white, which is not sign of root rot it seems? Plus, I've never overdone it with water and the pot has several drainage holes. But I agree that plastic isn't the best material.
What I'll try is add new soil to this pot as there's still room in it, and see if it reacts well.
