I did a light defoliation yesterday and nutrient change today. Plants stretched more than I thought for the breed, but seem to be starting some nice bud formation. I purchased the PH Perfect by Torus to see if it does what it claims. I've ran it for a week now and didn't have to adjust ph once. It kept my ph between 6.0 and 6.3. I'll keep posting my impressions of the ph balancer. After one week, it's performing as advertised.
