I can understand how lemon juice would attract the psilocybin and absorb it quicker
I'm assuming you mean salt formation? Well that'll happen in the stomach anyway as the oxyntic cells secrete 0.1M hydrochloric acid, and that's much better at forming salts with amines than most organic acids like citric acid.
Citric acid also will not catalyse or otherwise any conversion of psilocin to any other drug, active or not. Now citric acid has no effect on receptor binding w.r.t. any serotonogic drug, so that can't be the mechanism either.
The only viable explanation I can think of (which I'll consider a bit later) is that there's something else present in the juice that inhibits the breakdown of psilocin (like the way a flavanoid in grapfruit inhibits the cyp3A4 enzyme that's responsible for the metabolism of quite a few drugs). Now that would be fine and dandy if psilocin was metabolized by one opf the cytochrome P450 enzymes, but the main metabolic enzyme is monoamine oxidase (MAO) and if lemons contained a substance that inhibited MAO (an MAOI), we'd def have heard about it by now, as that'd mean amphetamine + lemons = a visit to hospital.
So, I'd have to say that it's almost definitely placebo in action
