Question on lock out flush and process

[Badchoice]

So I feel I need to do a flush to unlock my roots which is okay I’m about at the 2 week mark we’re fox farms suggest it.
Now with that said I’m a little confused on something and I really don’t f*** things up more than what I have....I’m going to use sledgehammer 3 gallons worth for my 5 gal DWC run for an hour as suggested.
Does that flush mix need to be ph balanced?
Is their anything after the flush that’s important like doing an extra hour of ph balance water (no nutes) drain than go back too nutes? Or non ph water to just grab whatever left over salts and that yucca crap?
any advice would be great I really don’t wanna lose my baby and this should be a good learning process for me to remember in the future when ph has gone down a bit don’t just add more nutes into the Rez Just top off with balanced water And that will adjust ph and ppm.

No need to flush DWC just do a res change.

Are you sure? My plant is showing signs of something, the leaf edges are curling up So I figured a flush to help any possible nute lock would be good....

Pics of plant and roots?

I'm positive

What PH do you set your nutes to? How high does it go before you bring it down? Are you using cal mag or anything with calcium? What is your humidity and air temperature?

Temp sticks around 72 to 76 at the plant base 69 to 73 in the Rez And about 40% humidity some time it goes down to 37 some times it goes too 45 50 but that’s where I live we got weird weather... I try to keep my ph 5.9 to 6.1 and I haven’t seen any crazy moments like “”I test at 2pm it’s 6 then test at 12am and it’s 5.3. And the photo is what I’m using been doing 1/2 dosage so far just don’t like how ff big bloom leaves the color behind but meh it’s bat shit what ya expect lol also I might want to add but idk if this means anything this plant if from a 50+year old seed someone gave me to try that they brought back from Vietnam.

Your humidity for that temp range is way too low. Should be 65% - 75% with them temps. I think your plants are drying up. Boost the humidity try to keep it around 70

I am also using FoxFarm. I'm using big bloom and grow big 3tsp each as week 3 req, plus 2ml cal mag and 5mg hydroguard (I may have the cal mag and hydro mixed up, not home at the moment). Per gallon of course. I was told by the hydroponic store owner to use 1/4, and people here say use less than what it says but I have no problem I don't think.

Here is a chart I go by for setting my humidity. Stay in the middle of the green columns is what I try to do

You've been sitting in the red.

Alright do you do the two week sledgehammer flush it’s got on the chart?

 

[N4M]

No I was debating on buying boomerang or sledgehammer but I have yet flushed my plants. I would take @Aqua Man advice. He said you don't have to flush. I trust his word, he is way more experienced.

Also, don't just up your feed dosage just because I am using full strength. I'm a noob lol. But it's working good for me. I do think maybe your plants look like that because the humidity is toooo low, very dry environment for them.

 

[Aqua Man]

I agree with @N4M humidity is to low for how hard your driving them.

Looks like light may be to strong. Can you download light meter by my mobile tools dev. And let us know the Lux value your getting?

Here is a thread I did on VPD that may help explain the effects of temp and humidity on your plants. VPD and its effects are a lot more pronounced with fast growth like hydro.

VPD (vapor pressure deficit)

Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...

Also do you have a fan pointed directly at it?

I have it pointed at an angle away to keep a small breeze on them but able to circulate and push the air up to the exhaust hopefully keep heat pockets out since it’s such a small space.

Well well aight the flush seems to be pointless on less your on full blown nute lock. And I hadn’t plan on upping the dosage I was gonna run 1/2 dosage for the whole grow

That was a good read and informative, seems I need humidity maker. Amazon gonna love me lol but I do wanna day thank you for the all the help

Just make sure no direct airflow.

Did you happen to check the lux? Think you may have a bit to much light on them

Wish this site was more mobile friendly I always got to rewrite my messages..

I recommend looking on Facebook marketplace and local Facebook groups for a humidifier. Also Craigslist. I got my $50+ humidifier for 15 bucks and it works great.

I would suggest a humidity controller as well. I have this one
