Is your friends formula for outdoors in soil, or outdoors in pots? Are your plants being grown in exactly the same manner as your friend's? (outdoors till harvest, outdoors for vegging and indoors for flower, the other way around, same schedule, same nutes...) Why can't you ask your friend what's up, since it's his formula...?

This is the main problem with adding so much crap to your mix. If you are inexperienced, you have no clue what the offending parameter is, and you have no clue where to start looking. Plus, you've already got the crap in the mix, with no way to remove it if necessary.

I'd strongly recommend you back-off and keep it simple. Once you get a few grow cycles under your belt, (and get to know how to successfully grow your strain) perhaps add one additive or ammendment at a time till you get to know it's proper dilution or application rates for your strain and under your growing conditions, and keep going from there.

BTW: It's time to transplant. Light kills roots, too :jointsmile:
