this is my first time growing, trying to keep it organic. i just need an idea of whats wrong with my plants ive looked up other post's and im thinking it looks a little like an iron def?? like i said though im a total rookie. the last few days ive noticed the yellowing on a few of my plants and now the leafs are starting to curl up on a few as well. i just checked the ph and its at 6 is that a huge concern? any feedback u guys could give would be a huge help to me thanks
