Leaf problem, help needed

[donpepito]

Hi to all!

I´m having problems whit two of the plants. Soil is the growing medium, and they are under a mars hydro lamp.

First two pictures are from a 5th week flowering plant.

Second pair of pictures are from a 3rd week floweing plant.

I think i have a problem whit water (too much clorine maybe?), ph or nutrients.

Thanks in advance!

What are you feeding it and what's the soil mix?

https://www.terrafertil.com/fichas_pdf/growmix_multipro.pdf is the soil (sorry it is in Spanish)

And the https://topcropfert.com/en/index.html Top Crop.

I just added another picture with more information of the soil.

Overall, she looks hungry.
It's important for nutrient uptake to keep soil ph close to 6.5
You need to be able to monitor what you're feeding them to eliminate a ph lockout that is creating the issues.

I control the PH every time before watering or giving nutrients, and I keep record of everything I give to them. I have a little problem whit Top Crop as the information of their products are not the best

Can you give me an example of a PH lockout? And should I flush them and then start adding nutrients again?
