After more research, I don't really need this. I'm providing plenty of cal and mag via the dry amendments during top dress. It works fine for what it is.
Works well, although I suspect it was too little, too late for the autoflowers in this grow. Next grow will have some pre-mixed into the soil and hopefully more readily available for the plant without burning it.
What an introduction to Mephisto Genetics! Looking forward to growing more of these, especially if this was just a freebie! Still have a while to go on the cure, but the high is very uplifting! I read alot about how topping autos was bad, but this girl didn't skip a beat and yielded much more than had I not.
@BruceBanner868, search etsy.com for "plant trainer" or "plant bender". If you have a 3d printer or access to one, there are several free plans on thingiverse. Good luck!
