Please help with problem

So around pre flower i had a problem with N toxicity I flushed the plants a little and gave next water plain PHd water.

After that ive been having too many issue with my plants.
From what i researched it was calcium deficiency and gave around 1ml/l calmag on the next water where i started again with less nutrients. The deficiency still seemed to progress a week after.
I am getting rust spots and yellowing on the outer tips of the leaves which are more shown in the light. I am also getting some mottling across the leaves which is progressing on the top and bottom of the plants. The plants are now flowering. I have also attached some photos for your reference.
The issue of yellowing of the tips seems to come from the bottom leaves and on the top growth seems to be the rust spots mostly.

You shouldn't flush organic soil, this has imbalanced the soil and took away from it all microbes and bacterias that were working hard into it, since the start, to produce food for your plant.

You should take a look at this thread if using biobizz.

Hello everyone, idk if this has been said but I wrote an email to biobizz to know if they created a feed chart for autos and they told me this :

Thank you for contacting us.

When growing autoflowers with Biobizz, our recommendation is to plant them in Light•Mix and use our Nutrient Schedule for All•Mix. In this way, we give to the plants lower doses of liquid products, as autoflowers tend to be more delicate and do not enjoy nutrient-heavy environments.

We have attached a copy of our Nutrient Schedule to this email so you can download it and check it every time you need to water your plants.

We hope this info is useful. Please, feel free to get in touch with us again if you have more questions about the Biobizz products or how to use them.

Green greetings,
Team Biobizz

maybe som1 is still troubling searching for it.

For immadiate results on recovering your plant, you should try to use mineral based fertilizers but i dont use them so i cant rly help...
Indeed I'd keep giving the biobizz nutes.
