You think buds lose weight if you wait until the leaves start fading to harvest? LMAO. We are talking about a weed here, not a fruit bearing tree. And fruit bearing trees are typically harvested early because 1 they drop their fruit (ground fruit is not useable) and 2 it takes time to get to market. They pick strawberries when they are still green/white in Mexico and ship them far north; by the time they get to their destination they are almost ripe-fully ripe. But anyone who knows whats up will guarantee you a frozen strawberry that was allowed to ripen on the plant and then flash frozen is healthier and better tasting than one picked to early. And if we want to talk about roses, I think fresh cut roses fucking stink. However old rotten roses start to let off a nice dank smell. I like my flowers well ripened. Obviously you dont. To each their own. Do you only eat green bananas? Because they get picked when they are green so that means that is when they are at their best? Personally I wont eat them until they are covered in at least 50% brown spots. Its all about preference and most people prefer ripe fruit or have never even had it because soooo many people rush to harvest.Then it's an ACTUAL Molybdenum deficiency. Sure leaves do that in the fall/autumn.. but contrary to popular stoner belief.. the fruit/flowers should be harvested long before the NATURAL reddening(Molybdenum release) occurs. Think Apples. Oranges. Roses... All of them don't yellow/redden until after harvest. It's an inverse reaction to the slowing of photosynthesis. You will get plenty of pot. It will smoke just fine. BUT... your yield and quality are being affected. Doesn't matter who comes in this thread and tells you otherwise. Plants reddening and purpling to the extreme is normal but not supposed to occur until after harvest. Simply put : Because red leaves cannot photosynthesize, therefore NO MORE BUD can be produced.
