What’s up ppl? I’m still new to growing and I don’t know how to count the weeks as far as seedling stage an veg so I’m a just say that my plant came out the soil on dec 22. I’ve been doing a lot of reading and have heard many different opinions. My question is do you use cal mag only when you have deficiencies or is that something that you use on the regular? I’m growing blueberry auto in a 5 gal smart pot in fox farm soil with a 300w led mars hydro. I haven’t given it any extra nutrients or anything just distilled water. And also when should I start using the fox farm trio? Any tips or or input would be greatly appreciated. Here are a few pics so y’all can see my baby.
