binaryselections

Hi I am doing my first grow under two ts1000 and my two binary section autoflowers, both landlocked funk. Both growing in FFOF with nature’s living soil super soil mix and are on week 5 so I just top dressed them with some worm castings for flower. I water only with ph’d water, no nutes.

Please see attached picture, no issues so far with this grow and nothing super of note, but I have no idea why the leaves are twisting. This is my first grow and i’m running four autos under 300w led in ff ocean forest with dry amendments.
