Indoor Professional cannabis growers!

[organic]

Have been looking about at mass produced legal cannabis grows. One thing i notice more then most is that the majority of leaves / plants are still green come harvest time.

So why do so many forum users push >> the leaves must be yellow.

I know the reasons why, but how come the mass produced crops finish green when they are being closely monitored and grown using with the best of the best of everything.

Even a large amount of outdoor grow photos I have viewed finished all green.

Thats not something Ive noticed.
Where have you been looking, were they auto's? Were they definitely at the very end of there life?

Everything I grow gets a good 2 week flush, so the plants yellow in the end as no nutrients left.

I have had only a very few of my plants leaves turn color before harvest.I go by trychome color when deciding to harvest not leaf color because plants are all different and are ready even though the leaves are still green.You can leave a plant go farther until leaves turn color but there is a point where the thc will start to degrade if left to long.

Does it stress the plant at a time when all it wants is to feed and to pack on weight? clearly shown by self harming and eating its self. Would you go on a diet if you wanted to bulk up and put on weight, no you would eat more.

The last two weeks or so are when the plants swell up, the final push so to speak, but there's no fuel left in the tank because its been starved for xxx amount of days.

This is the route I am taking, I will check at the 8 week mark and decided how much longer to let each plant go. It seems silly to say at week 6 i will start flushing for week 8 if that plant wanted to go 9/10 or more weeks then you just starved them at the worst possible time.

I was curious to see why so many want the plant to eat its self. after all we dont smoke the fan leaves so why does it matter if there green or not

Im new so this is only a guess from what ive read, but at the end isnt waiting just making the smoke stronger? From what ive seen they seem to max size before leaves yellow, but still mature for a couple weeks. Would make sense if harvesting for mass weight to figure out the time/weight relation and base it off that. Also see curing highly recommended but I doubt many commercial growers jar their bud for a month? Again just guesses:dunno:

This argument works on two incorrect assumptions. 1.) That leaves are the harvested product and 2.) That both the soil and the vascular system of the plant are devoid of nutrients the second you stop feeding.

I do not understand what you mean by assuming the leaves are the harvested product and 2.) I do not think you would assume that from what he said. With the assumptions put out in the first post, he's saying a flush and two weeks of no feed when the plant is "most actively putting on weight "is not the best thing. The flush won't get rid of everything from your soil but it will drastically cut it unless you're in some super soil that's decomposing and replenishing nutrients quickly.

If I'm wrong or way off correct me I just smoked :smoke: I could be looking to into this - I need to clear my head and look at the past year's BOM/NOM threads.

Huh.. medi where do i say you harvest the leaves or even mention that. I am a bud toker not a leaf smoker. You may have read it wrong I said we DONT smoke the leaves so why the common perception that the plant must be mostly yellow before harvest.

The soil clearly does lack the nutrients if the plant starts to feed on itself to survive and in the process turn yellow because if there was enough of a food source the plant would stay green.

My soil was rated at 2-4 weeks worth of sustainable food for normal house hold plants after which time intervention by way of me feeding is the only way any plant not just cannabis will survive unless you amend the soil at the start or start by applying a food source, they wont last very long.

I am just interested why the professional grows I have looked up come to harvest all green. Theses are grown under strict guide line aka medical so they are growing the best possible weed using the best lights, nutes etc.

Are the powers that be doing it wrong then?

The assumption that yellowing leaves is a sign that the buds themselves are starving. It's a sign the buds are taking in the nutrients from the leaves. My second point was that once you stop feeding and just water for the last two weeks you're trying to use up the last of the nutrients in the soil/vasuclar system to cleanse the bud of any residual nutrients. Also to make a third point you generally start the cleanse/flush when the trichomes get to a point where all you're doing is finishing up maturing them. My plants don't put on the most weight in the last two weeks before I harvest and I'm a TLO grower so nutrients aren't a factor. I'm really not trying to ruffle any feathers, I was under the impression this was an open discussion about the topic and was adding my thoughts.
