Yep don’t use PK Tee in veg mate. As above, wait until pistils showing. Or even until you’ve got small “pom pom” buds forming. Then add weekly or more. Depends on strain etc. And your medium. You’ll need more frequent applications in coco as it holds on to f*ck all.
Are you in soil?
The PK Tee is awesome stuff. You can really get it properly aerated and active and you’ll see great results. Make it as strong as your plants are happy with. It’s unlikely you’ll go too far unless you’re mental as it’s organics so kinda self regulating in many ways.
