Switched to flowering roughly 3 weeks and some day...

would need to see how this progressed. it didn't happen in the course of a few days. each brand has their own esoteric ratios of NPK et al... so the dose is esoteric too. ppms/ec and ratio of nutes is apples to apples communication in this regard. this is for soilless/hydro only.. not soil.. though over time it would average out in similar amounts, but some ingredients of N for soil nutes require a much higher resting ppm in th esubstrate... you've got a certain amount from the fertilizers, and some that has been processed by microbes in order to be absorbed through roots and plant-useable... anyway..this is soilless only.. N 120-130 -- in vege, but since you have some yellow/pale, i'd start here midstream in flower too... 100-110ppm in flower normally if you fed well before that point P 40-60 K 180-200 Ca 100+ Mg 75ish S 100+ That's a 1.2-1.3EC and should be on light side.. simple adjustments from there. if in soil.. good luck. not enough info here to diagnose with confidence. could glean som info off the soilless/hydro formula... just consider the frequency of fertigation .. with soiles it is every single time with 10% runoff to keep things even.. whereas with soil you often fertilize 1, then 1-3 water-only irrigations, then fertilize etc... The nutes that require microbs to break it down will need to be higher.. 166% higher give or take for N, for example... unless it's using fully plant-ready sources of N with no need of microbes, which is possible.. soil is a ton of unknowns.. hornet's nest...
