Almost harvest and ?cal mag with flush

Discoloration is normal at this stage... Think fall, all the leaf colors change! This is a good thing. No need to add cal mag, just flush with RO filtered water for 10 days. I like to flush, and let the roots dry out, then flush again.

Totally normal! They should show autumn colors during a flush...

it is all part of the flushing, you will see fades of color in some strains, it is really fun to watch, you could add black strap molasses unsulfured and flush with that as a sweetner for your finshed buds, but stick with water and you will do just fine, sit back and enjoy the color show, it is the plants end almost
