What should an adequete range of ppm should you have in the last week of flowering. I have been told around 1600 ppms but would like more opinions. And how much of a ppm increase should I have each week?
I run multi strain rooms, each room has it's own res. I don't go above 1000 ppm, I change nutes every 7 days. I live by "less is more". I run nutes up til the bitter end, no flush.
I run a couple different strains and non have gone over 1300ppm. I usually raise my nutes about 150-200 each week until I reach 700-800ppm during veg and then increase to 1k at switch over to flower and bump to 1200 after a couple weeks and hold that to the end. I feel like any more is wasting nutes. However it definitely depends on the strain as some are finicky eaters and some are hogs. Typically the sativa strains are more finicky and the indicas are more hogish.
