Worse symptoms from 3-4 days.Gotta get them fast.Help Please!! :)

[CookingRolling]

The pictures are from 4 plants it happend something like 4 days ago.And it is spreading fast.I don't know if it is ph lock or other deficiency so please help me . I water them with 6 to 7 ph everytime i don't have a EC pen though :(.I did a sample test from the soil with destilled water ( 10g soil 20-25 ml distilled water stiring for 5 minutes then letting it sit for 1 hour - It came 5.9 the one and 6.1 from the other plant - soil was taken from the roots).

The 2 yellow leaves are from a plant that doesn't have those yellow cirlce symptoms but it is losing leaves fast... Those are 2 identical variaties 2 different plants

Those are 2 identical variaties 2 different plants


Really don't know if it is leaf septoria or Cal-Mag deficiency...

Thanks all for help and fast respond.

Need to see the whole plant but i would guess overwatered.

I'd also like to see the whole plant

Sometimes heat gets as high as 30-32 celcius for like 3-4 hours ...

So your soil is at least that hot, much higher if in direct sunlight. Cooks the roots so she starts gnawing on her fingers.
Edit: looks like they are inground and mostly look green and healthy. Bottom leaves are just finished.

Keep those temps down. It's ok if it gets a little to hot for a few minutes at a time, but prolonged heat exposure will start the take it's toll

Damn really thanks for the info guys . So the conclusion is these problems are from the heat on all of the plants ? What to do with those leaves to cut them off or leave them ? Shall i continue to water them like i do with Ferts i mentioned above ? Thanks really.

I have 2 fans blowing so air circulation is moderate to good

That is from heat also right ?

So, 30-32C is 87 - 89/90F and you're saying it is like that for a good few hours almost every day? If that's the case, I'd be thinking about a way to cover these guys up, maybe with a shade blanket or something?

Your fans should not be blowing directly on the plants. You want the air to move around the leaves and through them, but not directly at them. If you put a shade netting up it should help keep those leafe temps down. (but after looking at your pics again, I see that you are in a green house of some kinda so really air circulation is going to be KEY!

The only other thing that looks odd to me are all those white dots. I'm not an expert (by FAR) but I always thought little white dots on the tops of your leaves could mean mold? What's your RH? with those high temps, I'd be worried about your RH levels getting to high and ldetting mold breed. (Again, don't freak out, I'm not a pro here just thinking out loud)

Thanks for the help.After doing a lot of research i think it comes close to Leaf Septoria and heat stress.I don't think the white thing is mold because i don't have on the buds.I have some really serious catterpillar issues so i spray them with powerful chemical pesticide nothing else works.I'm thinkin it could we the pesticide + pesticide PH which i didn't measure...

Mold only on catterpillar damage in the buds where they eat them.It could be from the humidity because i spray them and when i say spray i mean i soak them in pesticide and turn fans off until they dry up.I dot it in the morning for them to dry up faster.

Humidty is - daytime -40% - 60 % MAX - and night 60% - 85 % - MAX because it is humid in the region.

Any thoughts :P

Not sure where ya got the pics but thats not leaf septoria.

There could be more than one thing going on.

Overwatering for the bill for some, aging fits the bill for some.

Pics of the white powdery stuff on the leaves close up may help.

Pics close up of the buds?

 

[Beachwalker]

Mites and yellow leaf spot is my opinion but I could be wrong

 

[Aqua Man]

Mites and leaf spot septoria it's my opinion but I could be wrong

Spetoria has a dark black ring around the outer edge. Definitely could be some bug damage.

Like this.

Oh I know what septoria is believe me I dealt with it for a long time, the more classic septoria presentation I had indeed had the brown circle with a black ring

In my opinion this looks like yellow leaf spot, also a type of septoria but I could be wrong
