Wondering how close I am to Harvest here? These were all 50-60 day strains. Back Left CK leaves are lightening up like mad...the others are following (Currently on Dragon Force and boost) but the purple (Front left of canopy) still light pistils! No Good Trich pics to see amber!

@NorthernFrostCannabis I believe the idea of flushing (and I am neither for nor against) rallies round the fact that this is the only fruit you really dry and smoke! When the plant loses its water through drying and curing, the salts come out of solution in the cells and crystalise in the flower; this leads to harsh burning, sparking and the "Black Ash" phenomenon. As a counter (For debate only), you don't dry strawbs or anything else for smoking so there is no other real comparison out there (Apart from maybe some natural psychedelics or something similar). The only close comparison I can think that shows how salts can affect the smoke/smoothness/ash colour/burning out is counterfeit cigarettes. If you buy a legit brand, light it and leave it in an ashtray, it will burn through with a clean white ash all the way to the butt. If you buy counterfeit smokes, light them and leave them in an ashtray, you'll see they burn to black ash and burn out way before the butt. This is "believed" to happen due to the fact that brands "poison" their off cuts and left overs of tobacco with Saltpeter (Potassium Nitrate - KNO3) and that's what the counterfeiters use when making their cheap branded smokes (The 'poisoned' off cuts that is). If you smoke tobacco and have bought the cheapo version of brands, you'll defs have come across this. Suppose the idea of flushing is to make sure the extra Potassium you add during flower for boost or the nitrate used during grow gets used up so as there is as little as possible to crystalise in the dried product; giving a smoother and better quality end product. Stress as well...It can be productive in growth of cannabis as we light stress it into flowering, LST and HST all the time for better yields (topping/FIMMing, bending, supercropping, etc.). Plus, studies have shown that UVB, which is a massive stressor to the plant, is one of the reasons resin is produced...its a UVB blocker so the plant makes it to protect itself from cellular damage - we just have to make sure we use the right stressors at the right time! Again, I am in no way disagreeing with you...but its always good to have healthy debate around things! :) Cheers for the answer and happy and healthy growing to yourself too! :)

@NorthernFrostCannabis, bro, this is my first grow and I’m so glad you said this because I can’t believe people flush. It makes no sense at all. The plant draws the nutes out of the Leaves when coming to the end regardless so not adding nutes to water makes no sense to me at all 😂 cheers for the info!

Id wait at least 7-10 more days... You want all milky trichomes with some amber depends on your preference on how couch-lock you want It. This should help https://www.growweedeasy.com/harvest Happy growing!

Flushing... I will list some points that not only challenge the absurd impracticality and illogicality of this myth, but point out how the pseudoscience behind it is fundamentally flawed (as is all pseudoscience) and can be countered by what is known about basic plant biology. 1. Robbing plants of essential nutrients at any stage of their life cycle is NOT beneficial for growth. I challenge anyone to provide a single peer reviewed paper from a reputable journal that provides evidence suggesting otherwise. 2. If this was practical, wouldn’t you expect all big agricultural hydroponic growers adopt the same practice? 3. Plants take minerals into their tissues, from their roots via the treachery elements; i.e. xylem. Once these minerals are in the plant, they are there to stay, the plant does not expel them, unless it’s through senescence-driven abscission of leaf petioles. From the treachery elements nutrients are translocated into the phloem - the plant’s ‘blood supply’ - after being integrated into various biomolecules, or are used for various metabolic functions. Where is the logic in thinking the plant ‘uses’ these up in that last week of flushing, in order to avoid smoking them? All the N P K Fe Mg Ca etc. is still there. 4. For arguments sake say we counter the last point by suggesting these minerals in their ‘raw form’ will taste ‘hasher’ or ‘nastier’ in the form of pyrolytic breakdown products (formed when weed is burned) than artifacts of larger biomolecules of which these minerals/macro nutrients are now a part of, for example phosphorylated PO43-. Even if this was the case it still doesn’t correlate with the myth, as the transports steam in the treachery elements is measured in minutes not a week. i.e. a PO43- molecule does not wait around in these vessels for a week before subsequent translocation and modification. 5. If there was any truth to this myth, then plants grown in soil would always taste worse than plants grown in hydro. Why? Because obviously soil is not an inert medium you can flush for a week. And a plant CANNOT distinguish between a PO43- molecule that comes from soil from that of a PO43- molecule that comes from hydro solution (which also debunks another myth, but we’ll leave that one). 6. Are there studies that have conducted double blind trials to investigate if flushed weed tastes any ‘sweeter’ than unflushed weed. Again, need peer reviewed papers. And doesn’t have to be weed, can be strawberries or any other type of fruit. 7. What is the proposed mechanism to support this myth, and how is it consistent with fundamental plant biology. 8. How does starving the plant of food in the last week increase thc production in the trichome? Papers? 9. Given, under certain conditions stressed plants upregulate certain defence compounds, but they will almost certainly produce less inflorescence weight per watt of light. Growth is always retarded under stress - not promoted. Nutrient starvation is a form of stress. Looking for peer reviewed papers that suggest otherwise. Those of you set in your ways, each to their own and best of luck to you. Those who are willing to change their views in light of new evidence, or lack thereof, be ready for increased yields by feeding those hungry ladies right up until the second you chop.
