it's not just about using a product.. it is the fomula that results of all things you give...
so if leaf symptom chart says Ca issues, then you increase it. it doesn't matter if it is already included or not.. it is not sufficient.
There seems to be a little imbalance, but not enough to be nute lockout. also, ensure your pH is slightly acidic to rule out ph-related issues. Ca is one of the first things to have problems if too acidic. you go much below 5.8 and it's needlessly close to locking out Ca in a context of a home garden.

Ohh.my ph pen broke, that could be my problem.
how do i fix it? should I rinse the plants with clean water? and then should I continue with the nutrient table?

Purple streaks on stems can be genetic, but it's usually a magnesium deficiency. Make sure your pH isn't locking it out by keeping it over 6. Otherwise I think your plants looks pretty good tbh

Looks like a ph swing on some of them leaves.
Are you checking your ph in runoff? Or are you getting runoff?
One pot looks like it has perlite and the others don’t? Are they in different mediums?

There are many variables, see what all your ph balances are, did any thing change (heat exposure, over under watering) there’s a lot of plants under how many watts in how much space are they in etc …

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.
