No flower and flush

RollinRick
RollinRickstarted grow question 4 years ago
I have 2 questions: 1) Any idea whats happened with the one plant that has not flowered. Interestingly it was the plant I did not top and therefor should have been quicker to flower? 2) What point do I start flushing? Not convinced that i'll be able to harvest end of week 12?

Wilma may be a photoperiod plant. It can happen, but should be a very low percent chance if from quality breeders. 10 weeks in is fairly safe to call it... it'll double in size once you give it 12 hours of darkness each day before it stops growing, so you may want to prune it back if you will have constraints due to tent or growing area in general... too tall, too wide.. larger than light coverage are all possible. definitely don't go based on advertised flowering period... once buds look like normal buds, it'll be another 7-14 days?? You need a 30-60x magnier to see the trichomes. Flushing is an urban myth. the causalities given as to why you 'should' flush have all been proven bogus in studies. If you want to save a little mixing or money etc, that's fine too. This will depend on your prefered point in harvest window.. how much amber do you want? so, maybe when you see ~5% amber in most locations you inspect, you can give a healthy plant water from that point on and probably be fine. If the canopy is not so strong, you may want to rethink that. Not specifically about your current plants, but in general. You are also in soil, so giving some ph'd water for upto 10-14 days will give the fade you typically see.

Hi friend, To address your first question, Autoflowering strains can do that sometimes. They can hold the photoperiod traits a little too well and never flower. Changing your light cycle should kick her off into flower. I have seen success going down to 18 hours, but others had to drop all the way to 12. For the next question, Flushing is still highly debated, I personally stop 2 weeks before I intend to harvest. Cheers,

My best answer is genetics. Some will just start later than others even with the same strain. Same thing happened to me. The topping may have stressed the plant out and induced flowering? I could be wrong but it would make sense for an auto. You will absolutely NOT be ready in 2 weeks. Looks like you still have a solid 4-5 weeks left.

Not sure about question #1 but 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.
