In terms of n-p-k cal/mag what would you say are the ball park individual ppm values from ''full veg'' through stretch, mid and to finish?. It would be easier to stick to the growth stages rather than specific weeks for obvious reasons. I realise some strains are more finicky but put those aside.
I've found this very difficult to find info on since people are converting ppm in various ways along with very vague insights such as ''lower k'' or ''increase P'' by a fraction of what's on the label. For the most part we (or only I?) seem to run with a widely accepted ratio/total value and call it a day, with ought really knowing how little or much you can actually use and when.
To get the ball rolling.
As far as P goes, it was easy to find info since it's a focal point for many.
(From scholar) During veg the minimum value is 30ppm P. During the peak of flower the max is 80ppm P. However that value takes into account microbes that more efficiently transport P to the plant, after 80ppm P they switch off and go dormant. This would lead me to believe 90 to 100ppm P is max or possibly too much, in terms of long term build ups and toxicity. Just a bit of reasoning before P values to the best of my knowledge/opinion.
P value.
Full veg - 30ppm
Stretch - 30-50 max
Mid to late flower - 50-80
Final week (or 2) - 40-60
