PH drop???

[noreason]

as the plants eat their food ph rises gradually and ppm`s drop with a dialed setup....period......and....

This is generalizing, and probably correct, especially for RO water users, but, around the world there are plenty of different water containing different molecules. Fertilizers brands use different proportion of ions to reach a electrical stability that mean it does not affects pH, even if what is inside the fertilizer is different or in different proportion.
Plants are living organism and are all different.
Many other factors can be involved.

I do not use RO and my tap is at 0,2 mS\cm and I often see a raise in pH, depending on the plant stage and what brand of nutes I'm using, even if EC (ppm) value remain stable or decrease. I'm not talking about water alkalinity...

As HS stated , set ph lower in the mid to lower 5`s as yas swap out/top off/clean and refill rez`s for the proper drift upward so the plants can make use of all the macro`s and micro`s available at differing ph levels ......but....

The drift of a point is a good thing for me too. However I did a good harvest last time keeping pH at 6.1/6.3 stable for the whole run, thanks to the humic and fulvic acids.

Solution temps between 65-69 are paramount in importance with recirculating fast hydro setups or rootborn nasties can form and cause root rot/imminent crop death , but.......

I finished a couple of runs with 25°C water without any nasty. I would say I'm pretty lucky, however a chiller is one of the next item on the list.

ON week 3 of veg,running 2 dwc buckets 3.5 gallons of R.O water in the buckets.

Please stay on topic.

The topic is toastynoodles setup (which is RO) and their pH dropping (which is not nute/tap-water related).

Why do you keep going on and on about tap-water? It's not relevant to this thread.

Stay Safe!

I am on topic HS. My point is tap water.

I was ad I am suggesting to toasty to try to use a part of tap water, and I made an example to specify that for me it's not an axiom this:

Don't you agree? ok, no worries about but please do not attack me, thanks.

Having used Lucas for 10 years, I can reliably say that your 'deficiencies' would have been easily fixed with a full pH swing. A 'touch' of the green bottle makes for stemmier meds.

No thanks.

Stay Safe!

LOL...you were exactly who came to mind when I wrote that.

It's obviously not the pH swing...since I am fully in agreement about letting it swing where it wants.

When I posted in the past about the deficiencies you suggested adding epsom salts. I just like adding 2mL of the green instead.

As I said it's OK...

I don't notice any "stemmier meds" from my nutrient mixes and differing feeding levels...that's what works for me. It's all good. Do what works. Strive for quality, get there, repeat. For you, Lucas does it. Awesome!

It just won't work for everyone. Just like my advice won't work for everyone.

Try different things, see what works. Repeat what does, drop what doesn't, and simplify. That's my approach, and like you just trying to help others out with info that has worked for me.

Wow, you my friend are an Ahole!!

The science of growing cannabis!? I have been successfully growing for decades. Who the F are you, and why do you need to get so insulting?

Just because I don't have thousands of posts to my credit doesn't mean I don't have experience and knowledge to share...if we don't agree, that's OK...no need to get insulting!

I still stand by my original response to the original post. The guy just needs to add back water. Next add back with nutes. Alternate. If they look OK...just watch em grow.

No.. I don't agree. The point is that lucas works with RO the way the poster is using it. If it's not working... it's because there are other issues at play. IT IS NOT THE WATER! Thank you.

Again... suggesting that tap-water will fix this issue is naive and not helpful to the OP. Their original issues will remain and should the tap-water have additional buffering... it will only hide the issue until your reaction time is nothing and your plant is dead.

But why am I explaining this to you? You don't even use RO water and lucas. *shrug*

Damn I need better meds.


Thank you.
