What you point out is that everyone has different growing conditions. Advice should only be given in general terms and it is up to each individual grower to master his or her own growing conditions by trial and error.
My advice is always to give as much light as possibly and carefully observe how the plant react. This includes touching leafs to get a feeling for temperaturs and soo on. At any indication of unhealthy bleaching of the green color lower the light, and if heat is built up either move the plant to lower light or increase air curculation to cool the plant.
Unfortunate to many growers give to detailed advices, totaly ignoring that the growing conditions can be totaly different!
