High all! I have a Royal Jack Auto from Royal Queen Seeds about 2 weeks from harvest.I want a more couchlock high so im waiting for a little bit more amber.My question is how long should i flush?It's my first grow in coco,my last grow was in soil and i flushed a week-a week and a half before harvet but i have no idea what to do with coco..
Flushing is hippie science! Certain elements are immobile and can’t be flushed out! Stop feeding b vitamin and phosphorus the last week. Up your sugars and cut all base nutes. Honestly man, flushing is mostly bro Science! The elements that are mobile simply translocate from the leaf to the buds anyway! Why do you think the leaves change color
