EL PATRON (RQS Test New Strain)

The plants make beautiful buds. The leaves of the plants are now becoming more yellow. Faster than expected. Would the plants get too little nitrogen? In week 4 I planted the plants in a richly fertilized soil mixture. I thought this would be sufficient nutrition for the entire flowering cycle. But both the four plants (1,3,5,7) that I have enriched with RQS nuts, and the four plants (2,4,6,8) that feed BIOTABS, suffer from yellow leaves. 😧🙀👇 The plants are in Autopot XL pots, which means they automatically get water from a 240-liter container. Adding organic fertilizer to the water tank is not recommended according to the Autopot instructions, because of the possible clogging of the tubes. 😰 Do the plants suffer from a nutritional deficiency? 😏 What should I do? 😕
