Starting to notice the leaves of both plants going a bit yellow. Im guessing this is due to their lack of nutrients? Any suggestions or tips for this stage of the grow (minus nutes).

Yellow discoloration again
I'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?

Желтеют листья.
Всем привет! Выращиваю первый раз, сорт Auto Opium, растению месяц, нижние листья начали желтеть и вянуть, это связанно с переходом на цветение? И за какое время растение будет готово к харвесту? Заранее всем спасибо за ответы😄💚
