Normal I'd say yes. but by better feeding I think we can prevent it from starting at 4 weeks in flower by controlling our feed better.
The pro's will pop in and correct me for sure but I'm not getting that fade at 4 weeks now after adding Cal/mag to my nutrients starting at week 3 of flower. I 'm also not dropping Grow / nitrogen? out of my feed and keeping it at veg levels right through until I taper everything off starting around week 9. I don't add it to my nute mix until week 3 of flower because this chart says that's when I need it & just basic veg nutes until this chart says to change up........I've stretched this chart to 10 weeks and finishing at 11
