I’m so glad you posted.
You’re about to make the exact same mistake I made on my first grow.
Check my post history and go right to the bottom. That’s what you get when you hold of feeding.
You’re doing one step better than I did because of the early calmag but I don’t think it’s enough.
I feel like I already know where you got that info about 14 days, but I don’t like to bad mouth youtubers.
I started feeding after I saw the second set of leaves, and I already had food in the soil.
Waiting to feed autos in coco is a bad idea imo. But this only my 3rd grow and I’m still ready new. Someone might have a better reason to do it, but from my experience you just stunt your plants.
