So you're in a seedling mix, (unbuffered, most likely) haven't fed 'em and have crappy lighting. Time for some changes. A seedling mix is a bad idea for more than seedlings. Too acidic, no 'body' to support
Lol no no no no no no, i do not have any plants that are bigger than seedlings in seedling mix. I only have my seedling in a seedling mix haha. My bigger plants are in real soil. My Wonder is in all potting soil and my Diesel is in a mix of potting soil and top soil with extra peat moss and perlite that i added in myself. And i know the top soil was a bad idea, i now have a big bag of growers mix i am going to use for future plants.
