have you heard about foliar feeding with silica based nutrients? there was a study on icmag it had great results:

hey man, i also do 12/12 from seed under a 150 watt hid, and it takes me about 3 weeks to get sex. ive vegged for one week in hopes of getting pistils in 2 weeks total, but it still takes 3 weeks to find sex. males usually show a couple days sooner than females.
i also top once, right before the stretch (3 week mark) but i never thought about lsting the four main colas. im going to try this with my grows!
as soon as you saw the nitrogen claw on page 2, you should have eased up with the feeding. that is nutrient lockout due to salt buildup. i would flush with the size of the container, let her drip/drain, and then soak the soil with a 1/4 feeding solution.

yeah, prob I was spending too much time on a beach
) k bro i feel ya, i just though simce i'm not using ro water, and its ~8 and some ph+ from silicate, thought that might be too much, better ask than later be sorry
anyway, kites in a land where i was born are considered to bring luck, and so far ur tips did it hehethanks man!

hm its 3am, after 8 hours finally just finished baking bread and reading 700pages book, im like drop dead tired but from a quick look not too much info or pics in there, there was one more link in there, but will check it tomorrow, anyway got lots of time since plants will still be 7-9weeks in flower. i just had way better results when not stressing the plants with spraying, leave edges were wrinkling, but maybe it was a because of heavy spraying till the drops start leaking on soil from leaves, maybe lightly misting that would do better. but really doubt cause fan blows away all the water withing few minutes..
thanks man for the input, will check that out!

yeah thanks man but no thanks, it's a fresh 5 weeks old soil, salt builup??? you're reading from some bad sources. i watered 3 days ago with 1ml of organic grow food instead of 3ml and plant in the evening was getting better, next day it kick off, today she's still happy. man pls flushing topic hurts my eyes already... tired of debating
you're prob growing some indica strains, i went for pure sativas 12-14 week flowering strains, zamal only few days ago started showing pistils
cheers man, thanks for sharing ill check out ur threads tmr

yeah like old saying "morning is smarter than evening" dunno if that makes any sense, just a word by word translation from my language hehe.
Found in that thread another link with more detail growing. For me those sprayed leaves looks a bit more like they were made from plastic lol. Can't wait to see if there'll be any difference. But i'm pretty confident about it. Sativas could really benefit from fatter stems

Kite can you give me more info about leaching the medium? I'm not sure I'm following, at what time it is being done? Like before growing or during? How can it be causing a spurt? Is it not short-term stress spurt? Or are you just messing with me lol?
I thought leaching is a synonym of flushing..

yes in the morning means the lights have beenoff for 12 hours so it might not be morning but the logic is the same. flower and root growth are more prevalent during night and thc degrades with exposure to light. it also allows the plant to use up stored starches so curing will be easieryeah like old saying "morning is smarter than evening" dunno if that makes any sense, just a word by word translation from my language hehe.

i have experienced the growth spurt after a leach. i chalked it up to me using a 40 lpm (commercial grade) air pump with a 6 inch bubble disc in my water before hand but im wondering what would cause it with someone who doesnt use such a high amount of oxygenation in their water.
i have some recommendations based on research iv been doing on cadmium remediation from soil. these are all based on real life studies, the most surprising thing i found was they were able to remove 52% of cadmium from clay soil(which has a negative charge and is notorious for its ability to hold heavy metals) from flushing with plain water. another study demonstrated that cadmium can be oxidated by hydrogen peroxide over the course of 50 or so minutes from between 30->70%. supposedly it turns it into a bunch of different compounds im not exactly sure what they are something ferrous... nickle oxide. dont quote me on the names. another study found that waste water and sludge could be treated with coco or perlite to get a removal rate of 99% and 55% respectively. acetic acid was used as well as citric acid as a means of removing cadmium and other metals. acetic acid was 8% cadmium removal and citric acid was around 30% if i remember. its important to note that these methods all work in different ways. water flush removes it by leaching, h2o2 removes it by oxidating making it unavailable in the plants, cadmium is adsorbed by coco and perlite and citric acid and acetic acid leach it away.there is also evidence of introducing worms to your soil to digest cadmium and other heavy metals with the benfit of worm castings. soil microbes specifically certain aerobic or faculative anaerobes also help by digesting the metals. this is by no means a perfect recommendation i am going to have to convert mols and what not to actual amounts of h2o2, perlite, coco, acetic acid etc...
flush your soil before planting with water to remove cadmium. you should be running 5 gallons minimum per planter
use of 1 cup of h2o2 per 5 gallons during the flush will help oxidize cadmium and help neutralize it even further
to remove cadmium from fertilizers take pantyhose and fill a leg with perlite and or coco and or clay and tie it and leave it in your nutrient bucket with an airstone to brew with the fertilizer for a couple days. the cadmium will stick to the perlite/coco/clay and you simply have to rinse it out after and let it soak in a bucket filled with 1 cup h2o2and the rest water
every month do a flush of your soil with at least 3 gallons. use h2o2 in the flush and aerate the water for at least 10 minutes before flushing.
after flushing use 1 tbsp molasses with enough water to fill your planter and water with that as soon as possible. aerate this as well
2 weeks before harvest dont fertilize and do a flush with h2o2 of 1 cup per 5 gallons.
this can greatly reduce the uptake of cadmium and other heavy metals into the bud and will greatly improve the taste.
it is important to do the flush 2 weeks before harvest so that you can remove any cadmium and other heavy metals from the soil so the plant will be less likely to have it. not using nutrients the last 2 weeks will help with removal as well but it wont hurt too much if you leached the soil before the grow began, added the coco/perlite/ clay stockings to your nutrient teas etc.
its also important to note that both inorganic as well as organic ferts contain heavy metals and each batch of fertilizer will vary on the amount.

yeah, I've seen your advise in a 22 pages thread which I've been following from the very beginning. Do me a favour and press ctrl + f on your browser and type Cadmium and press highlight all and see how many times you mentioned this metal... Dude you're totally obsessed with those heavy metals..
I do not believe that in such a short time you can buildup a threatening amount of them in the soil which your body could not handle. Also I noticed that every time I mess around with the plants, it stresses them and it takes time for them to start growing again, sometimes an hour, sometimes a week, but when I leave them untouched and just watch them growing they start going crazy and look happy. I'm not that green guy who would like to live long and healthy life without heavy metals in my body etc. With all the radiation, unhealthy lifestyle, polluted environment and million other factors... this will not make my life noticeably better so I would spend so many hours stressing out on this particular subject.
I tried flushing, it disappointed me a lot. Caused turmoil in the soil-root relationship and plant made it's revenge on me. I do not see the point in it. I smoke once a week and my buds are smelling and tasting like freshly baked grandmas apple pie. And all of the credit goes to boveda 62% humidipaks.. fed all the way till the harvest.
I am not sure I am ready to go into all those endless hours of studies and researches that have already been done, I have a lot of things in my life to be running around, so I just chose to parrot people who has lots of experience and outstanding results. I still do a lot of reading daily taking into consideration all of the opinions, but somehow I always lean back on people whose results make my eyes swell.. I do not have airpumps, (de)humidifiers, air conditioners and I am not able to get them. Maybe when I will build my own house, I will make the room specially designed just for that, I will also get my hands on vegetables and fruit growing, then I will be investing way more money/time/researches, but for now I enjoy my 3'x2'x3' grow room with 2 plants in it which makes me smile every morning.
Thanks for your input, but h2o2/flushing and in all other ways disrupting micro system in my soil is just not for me. Also in a way you say it I get to imagine that flushing is like garbage truck which comes over to pick up heavy metals trash every month and plant packs it in bags and happily trashes.. I do not believe that those metals are removed from plant and moreover after you flush you feed a plant with nutes again.. Again they are uptaken.. So for me it seems that the only thing you achieve with it is keep your soil "heavy metal"less in expense of f*cking it and the plant stays the same just stressed out, ill and unhappy...

Flushing during the grow to leach salts and push growth is a grand thing. This is what is occurring. The plants think they received a heavy rain so they ramp up transpiration to pump out the water and get O2 to the roots. The raising of transpiration raises the growth rate. Simply pour three times container capacity through them of water immediately followed by adequate feed water of enough volume to fill the container. It is a great and useful tool that is like rebooting your computer but its plants bro.

well there have been studies proving cadmium and other heavy metals are present in marijuana smoke. there are even studies using cannabis for phyto remediation of soil because it uptakes heavy metals at such a high rate. the studies are there proving water, perlite, coco, and h2o2 will remove these metals. if you want to see the studies let me know. and an airpump is going to help you out alot and you can get one at walmart in the pet section with the aquarium warez.

yeah i tend to stay away from shark meat lol. and by flushing you are definitely removing up to 52% of it.

omg I even don't know where to start.. My head is so messed up, thinking are you serious or are you being sarcastic? It's just that all those numerous times you were saying that flushing is for toilets and now this.. If you do not mind I'll put some thoughts that blows my mind at the moment and I would greatly appreciate if you comment on them.
1. my plants are still quite small(10"). First 4 weeks I was watering with 0.5L in 1gallon medium every 2-3 days, the when I upcanned a week ago I water with 2l in 5gallon pot once in 5 days.
Do you think I can have salt build up after 5 weeks from seed?
What do you think should be leaching schedule? Once per 4 weeks? once per 8 weeks? Roughly, so I could get a feel of it.
2. Does that method apply both in veg and flower? If yes just don't answer
3. again pH.. since I am using tap water and I'm not able to store like 16 gallons of water to sit for few days to evaporate, if I'll leach with 8.5-8.7pH water will the soil still be able to buffer this? If yes just don't answer to this. Sorry for repeating that again and again..
4. When last time I was running a water through my 3 gallon pot, can it be the case why the soil became tough and lost all the fluffy property because I made too small holes in my 3gallon bucket. Can you comment on the speed I should apply the water cause I have the feeling that because I was pouring more than it was leaching pushed out all the oxygen from soil and that's why I had so many problems after doing so.. Should I also apply h2o2 as recommended by applepoop on the previous post?
5. Because I upcanned a plant only a week ago there's probably still lots of space which is not occupied by roots. Because plant will not be able to transport all the water from medium, but only where the roots are, could that cause any problems like fungi or root rot?
please answer only those parts if they are worth attention, the rest just ignore. Just before stepping into something new I want to be absolutely sure what I'm doing so I would not do something like topping the main cola 20 days into flowering on my first grow lol...
again, thanks for staying with me bro..
p.s. today I got surprised, Destroyers colas during night time grew more than during day hours.. But that is only last night and yesterday comparison..

And
That is what Kite High is talking about simisimis. A preharvest flush would theoretically leave nothing in the soil for the plant to feed from, while flushing and then adding back in nutes will.

man, but you are leaching the soil and right after you feed them with nutes, i do not get it, you remove it from soil, not from the plant, and then you add some more right away.. so plant is just uptaking it.. ull be smoking plant in the end, not the soil.. i don't get something here :/
