What is happening with plants?

The plant started showing brown spots 2 weeks ago now the leaves are yellow with brown spots, don't know.. Can be calciun or Mg?


The water I use for irrigation I always put it at 6.3-6.6 ph, 2 months ago of the last calibration of the meter, tomorrow I will calibrate again, but I do not think it is this.

Water for irrigation at 21c. Temperature between 17-25C and humidity on 40-75(should solve that)

I'm using canna fert, las irrigation was the first with pk13/14, did't used the terraflower (only for 1-2 irrigations and eith the half of the table was showing) did like that becouse normally use the same genetic and this one ever worked well with low fert, and using land rich in fertilizers.

They are gonna want pictures of the whole plant.

Can't at moment, but all the plants are like this one high part of plants are little yellow with the brown points too...
If can i will put picture of whole plant, but don't know if will can..

This indicates to me a bug problem. Are you sure you dont have mites?

Hey! I'm sure i had spiddrr red too s if times, don't know if can be other type of mites...

Also the brown yellow oxid poins u can see at the leaf the same point behind the leaf is lime a white point..

Can be calcium?

Maybe, but this usually indicates something is eating the cells, a lot of things can do that. Mites just do it quicker and the leaf you showed is tale tale

That's not mites. Well maybe broad mites. Get a whole plant pic. We can only guess until then.

Drop your ph down to 5.8 and see what happens.

I also see severe N tox.

Nitrotox doesnt do that in my experience. It gets dark green then brown then dead. The fact is I have not seen death like that without a bug or serious issue... Hence my mite theory. Broad would be indicative. Which ya cant really treat as they lay eggs inside the plant
