Feeding until near of harvest causing no fading or cannabis fade anyway even if feed them full dose from feeding charts?

every plant is different. i learned that cutting of nutrients will make them fade faster. but many genetics will fade even if you keep feeding them with a max. amount. just check trichomes for harvest - the plants appearance does bot indicate its flowers quality 🌱💚

If they have been well fed their entire life, they generally won't fade, but not always. If they have had a medium feeding schedule or pre-mature end to fertilizers, then yes, they generally will fade, but not always. "The Fade" is not a necessary process or requirement for determining harvest maturity. However, most people generally stop all fertilizers, feeding, supplements and stimulants about 2 weeks before the estimated harvest date and this may lead to a natural fading occurring.

It depends. I've had plenty of plants look nearly pristine at harvest and others have some symptoms, and still others show the fall colors (reds/purples). So, genetic variety is at play, here. Senescence can be a major factor, but depriving a plant of nutes for some silly reason will cause a fade. Not sure how starving something is a net-positive. Especially since most of the nonsense used to push this "bro-science technique" has been proven false or bat-shit crazy. reds and purples are gentics and/or cold temps at night. this is for the same reason colors change outside. the temps screw with the biological processes of the plant and it's slowly dying. Growing indoors doesn't necessarily follow that path. We control the environment to some extent. Even so, some plants likely still turn red/purple at end of life due to genetics in absence of cold temperatures, but not all.

It will fade either way. The plant is getting ready to die and that happens whether you feed or not. Genetics will be more of a factor in the fade than the feeding.
