Finally remembered to update this.
Girls are BIG. Over 2 feet tall and full of flowers. They are healthy and flowering. Getting used to how much defoliating needs to be done for flowering. These are fast strains so harvest should be in around 5 weeks. I will be flushing them for flavour. I noticed some tip burn for the first time this week but my EC is only at 1.5. Did a flush watering with only pH balanced water to dissolve excess salts in the Coco and may overwater this feeding to promote runoff and a better equilibrium for the plants after their mini-flush. This post was put up on day 23 of flower. Any advice is appreciated!
I hope your Delahazes have that notoriously great citrus smell... my last plant was a skunky/spicey wide-leafed phenotype, good cannabis but not the Delahaze I wanted.
