Inward bending, weird spotted leafes

Hey, need to tell you that your soil is mostly completly sucked dry of nutrients after week 4 with this plant size in light mix. The nutrients which you are feeding are not coming in time for your plant, it will get a constant back and for. Also i think you are missing cal/mag in your feeding plan. If you wanna stay organic with your grow in the longrun you should inform yourself more about nutrients and soillife. Whats best for it, how to mix it, that the soillife provides the nutrients even better to your plant.

I think it's probably humidity being so close the the medium. I would just take those leaves off before mold starts to catch..
