Nutrient blockage

Looks like you accidentally put ton of nutrients or ph lockdown more likely

I think I have a problem with nutrient blocking or overwatering (I watered several times without waiting for the soil to dry out)... I think I have a problem with liquid fertilizers... Because before I grew photoperiods in medium quality soil with "Or Brun" (a mixture of various manures and algae) and my plants were always in good health and gave me big yields... They are autoflowers! 1 Northern Lights, 1 Strawberry Banana and 2 Gorilla... I use a MarsHydro 150 watt LED lamp in an 80x80cm tent... Daytime temperature 22 to 23°c and 19 to 20°c at night... I use 20 liter pots with biobizz lightmix soil... I use advanced nutrient fertilizer every other watering at a rate of 3 liters per pot... perfect pH sensi bloom A+B 1.5 ml per liter Big Bud 1.5 ml per liter Bud Factor X 1 ml per liter Bud Candy 1.5 ml per liter Nirvana 1.5 ml per liter Sensizym 2 ml per liter I water with water or a mixture of water + fertilizer pH 6... My soil has a pH of 7 to 7.2 when I just watered... Even after having carried out several rinses with Flash Clean GHE the pH does not drop to its original pH which is 6.2 for biobizz lightmix...
