Potency question for growers

Has anyone who grows their own ever noticed that the later flushes can be much more potent/"different"? Last night I ate the same strain I've been eating, the potency is always very strong, I usually eat 2 grams and then periodically re-dose as I feel, and have a fantastic, mostly clear headed trip. Last night all I ate was 1.8 grams worth that was put in a chocolate and stored in my fridge. Literally within 10 minutes the visuals were pretty noticeable and I grew more confused by the minute, not scared but very intensely confused. I've had this EXACT same kind of trip before, it was just "different" the visuals were much faster and erratic, almost sloppy. Guess the question after all of that is, I know potency can vary wildly between even the same mushrooms, but is it possible that a more mature/aging mycelium produces mushrooms with more baeocystin/norbaeocystin as opposed to psilocin/cybin? There was just something else to the trip, not much introspection, just literally passing the minutes so the confusion would clear, not a bad trip, no depression or fear...
