Hey there 👋
I’m growing some green crack now too! I’m a few weeks behind you, but I have grown other fastbud strains in the past. I have noticed they run a bit longer, it all depends on your temps, When you start counting weeks ( I’ve always started after germination, but I’ve seen a lot of people waiting for first true leaves), and what you are feeding. I think yours look great- hang in and have patience. I’ve never had any issues with their genetics
Happy Growing 🌱
