Flush and starve plants during flowering??

another victim of leap before looking. you should really read my threads before you go snatching random pics to prove your points. those plants you posted are suffering from fungus gnats not excess nutrients as you are trying to make a case for. which is why you prolly shoulda read some of that thread before posting those pics. anyway continue.

Hmmm, fungus gnats never induced a nitrogen deficiency in my plants.

settle down children. don't make me call your father.

anyway you n00bs carry on with your green harvests and harsh weed, i'll carry on doing what i'm doing. we'll just agree to disagree.

really? little maggots chewing up all your root system never cause your plants to have issues taking up nutrients? plz do tell.

The secret is: quit treating cannabis like it's unique and quit buying in to cannabis specific nutrient lines and their schedules. You'd be amazed at how lightly you can feed a plant if you just feed the plant what it wants at all times. When you're doing a better job tending to the plant's nutrition needs, you shouldn't need to 'flush'. To each his own though as we reap what we sow.

Seriously though, cheers and good luck in your garden. I'm not here to give you a hard time, I'd just challenge you to test whether you're doing the best possible job you can for you and your patients.

um no, i was still talking about the fungus gnats. please tell me about that part. i don't care about your nute regiment, i'm on organics now. i wanna know how you can have fungus gnats eating your roots to shit but your plants don't suffer at all.

There is no question that plants have a better resistance to pests when fed exactly what they need. That being said, they're not immune. One of my hydro plants had gnats last month, the yields were down but it was an otherwise healthy plant with fragrant, resinous flowers. I saw maggots, I saw the gnats, I just put a yellow sticky card on top of my rockwool block and stayed the course. Healthy vigor can often times outpace the damage pests can do but pest management is more-or-less priority number one for the indoor grower.

Hang some sticky cards and keep things cleaner. Just be glad you don't have mites.

Its amazing how store bought soils can harbor so many bad things like Knats.

As far as flushing goes, I found a thread about flushing agents and how they are just light sweetened water, the sugar, increase osmotic pressure.

Sweet!

Store bought soils--yeah, you never the history of that particular bag...like the one last purchased.

Like--what specific location was that bag while in transit? Where in the pallet--on top, or inside in the middle? Where was the pallet during shipping? Rail or truck? Did the sun bake the top layer of bags on the pallet while the truck drove through 100 degree weather? How long was the rail car sided, closed and sat on the rail baking in triple digit temps? Days? Weeks?

Not to mention...plant available nutrients (breakdown time), and quantity and quality of the nutrient/fertility! Something you just don't really know for sure--unless you mix custom growing medium...from scratch. Professional bakers do not buy "bread mix"...rather they purchase: flour, yeast, salt, eggs, etc and mix their own "from scratch".

Cheers!

you gradually reduce nutrients over the last 3 to 4 weeks and plain water for the last or two...
the best way is to always use lower strenght
throughout flowering. people do alot of cooking and don t even check their medium stats...
flush before flowering and before week 4 or 5, then at the end. (that is, if you can t keep a smooth and steady regimen.)
peace

I am getting close to harvest (dwc buckets) and have been reading countless threads. Most people advocate 7-14 days in general but many of the replies are made by soilgrowers.

It seems like there are some growers that do not flush and it also seems like they are the same ones actually arguing based on botanic/biological reasoning.

I have started stepping down the nutes but I never fed over 1000ppm (hanna) so I am a little hesitant to stop feeding altogether especially seeing how they are 63 days in flower and still putting on weight.

I would love to hear from the DWC guys, seeing as this is the hydro forum and all ;)

Hi man.

my 2 cents...
first question to ask yourself.

WHat colour are your plant s leaves?

1: Are they a nice limey toned down green starting to evenly yellow ?

2: or are they dark forest green and/or scorched edges, rust coloured spots in middle of fan leaves?


In case of number one, bring your e.c down to 0.6 (300-400 ppm at 0.5 conv. for your hanna) for a week, then flush with cooler water for a couple of days.

NUmber two, you might have to change your solution right now and adjust ph to 6.0 and feed this solution till the end.

hope it helps a bit.

(less is often more....and yes especially at the end, watch them swell up and use what is within their metabolism)

i do 5 gallon individual bucket dwc and i've noticed that one of the signs that the plant is getting close to harvest is that it goes from drinking a gallon a day of 1.2ec solution down to half that amount. thats when i drop my nute solution down to .5ec (200-300ppm) for the last week or two

1.No they do not show any noticeable deficiencies except some very old over fert on the oldest fans.

2.They are a nice healthy green and the trichs are starting to turn amber

I am at day 63 (you can check my album or grow diary) and at this point I think at the very most I will do a 5 day flush even though I can find no scientific evidence that it will do anything but slightly reduce yield.

I try to let my ph drift from 5.2-6.2 but I am unsure if this will occur without nutes in the mix. Do I just set it too a ph and it will stay steady?

Fist of all Do not lower your Nutrients at the most crucial time when buds are getting heavier secondly were not growing out side so to say normal yellowing is normal hahaha keep it green although N is not used as much in flowering its wise to maintain a dent N level most issues occur when in 2 - 3 week the dreaded yellowing appears
and secondly can anyone tell me what NPK taste like REally now ????

They eat half the amount of water and nutes or just less water?

how much were you feeding max in flowering?

It makes sense to lower the solution as they drink less but as long as they are eating I keep giving them around 50-60% of what I gave them at max during flower.

I am at day 63 flowering and two of the buckets have slowed down on the nute uptake so naturally I gave them lower doses to make them drift properly within the ph-range. The biggest plant is still eating so I am giving her 60% of max nutes (590ppm). I do not think I am underfeeding her atm since I usually change the res before it is 100% nute free and in dwc the nutes are much more readily available.
