Hello I will harvest at the end of November. What...

they are showing clear signs of heat stress, the "saw" on the leaves are up. I do suggest making it more ventilated so the oil production rises, and only flush if you are using strong amount of nutes. The great professor of cannabis university once said that you should apply 600ppm from start to finish, same 2-1-2 proportion, and nothing more matters. I do like to add that black strap molasses chelates fertilizers on soil and help a lot on finishing the plant, so I do suggest adding it to your mix, and making it 600ppm from now on.

Eu pessoalmente, tento dar poucos nutrientes ao longo da vida da planta. Só dou nutrientes até semana 6/7 de flor. Últimos dias ou semana só com água, ajuda se suas reservas estiver acabar, pois ter uma erva mais limpa de nutrientes, tem tempo de cura menor. Bem se tem tempo para curar, lavagem não tem porque. Mas também para que dar nutrientes no final, não tem qualquer vantagem. Faça um teste com duas cepas iguais, ums com nutrientes até ao fim, outra com nutrientes até semana 7, só água daí para frente. Abraço bom cultivo

You don't need to flush. Best approach. The last 5-7 days. Pull your nutrients. And let water feeds and the plant eat whatever nutrients is left in the soil. You may see the plant eat a very small amount whats needed from the leaves. But, once you're through most of ripening. Lower your light % to 70-80% of what it was at it's hight.

Assuming the plants are healthy and no reason to flush otherwise... It doesn't impact mineral content of the flower (lab measured proof and common sense given existing knowledge base). This is how cell differentiation works. Flower is not a storage facility in the plant. That is not its function. The plant has no way to excreted nutrient molecules. Flushing phyiscally cannot change the mineral content of what exists in the plant. Impossible. Also, drastically shifting the chemistry of the plant probably isn't optimal. This is not a logical argument (doesn't mean it can't be highly correlative), but ... do you see people flush plants outside? Of course, not because it'd be absurd. blind taste tests show people have no fucking clue which flower is 'flushed' or not. Yes, i've done it. I'm a bit embarassed i engaged in bro-science, but it happens. I've done it since learning better, because i'm a lazy fucker that didn't feel like mixing up nutes and my canopies are most often strong and healthy enough to do it. This does not embarass me, lol, because i did it knowing it would have zero impact, give or take. Probably more efficient to get nutes from roots than to cannibalize leaves, but that is a guess. the extra steps invovled would require more ATP, which is the primary energy currency in the plant. That's the sugar that photosynthesis produces.

All I do is give water for last 10 days, as my medium has usually built up a fair amount of nues.

Btw you grow in coco, not soil. Otherwise you wouldn't water daily, you would ruin soil grow with such actions. And i saw no perlite, its smart to add 20-25% of it to any medium, better for roots.

High Snaqq, Plant is looking good buddy! I do not flush but I do only water for the last 2 weeks. There are still enough nutrients in the soil and leaves to fatten up those juicy buds. The taste from the buds are less sharp on your throath. But to archieve this you also need to let them dry till 62% humidity and let them cure for at least 2 weeks. You can use the humidity packs with 62% and a curing jar. This way you do not need to regulate it yourself. The buds are dry when the branches where the buds are attached on snap when bend 90 degrees. Happy Harvest Buddy! 💚

If you dont ovefed or had toxicities - flush is a myth. I tried it with soil grows many times. In summer was putting girls for an hour outside and pouring 20-30 liters of phed water through 20-30 liters pots, was doing 3 waves like this. Saw no need of it at the end. Good drying and curing sorts everything. Good feeding brings bigger results. Your plant looks nice, no need to risk with excessive amounts , because of rot issues. If you cut nutes and water same just eithout anything inside results will be smaller. There is no need to starve them at the end of bulking stage, you will loose weight otherwise. Have fun !
