I used to run 5.6-6.0 and was chasing issues that i couldn't solved.. switched to 6.0-6.5 and never had issues again.. if you look at the ph chart a few nutes drop off big around 5.8.. so why not just go up a little?
That chart is more for soil grows. When I used non pH Perfect nutes my pH would rise over 3 days to about 6.3 and I'd knock it back to 5.5 or so with a few drops of conc. sulphuric acid every 3 days when I did my top-ups. That back and forth made sure that all nutes got some time at optimum and the plants really loved it.I used to run 5.6-6.0 and was chasing issues that i couldn't solved.. switched to 6.0-6.5 and never had issues again.. if you look at the ph chart a few nutes drop off big around 5.8.. so why not just go up a little?
P.S. there is ZERO downside to goin up .5 of a point.. so why not?

AHH thank you!! i was looking for that second chart and just grabbed what i saw real quickThat chart is more for soil grows. When I used non pH Perfect nutes my pH would rise over 3 days to about 6.3 and I'd knock it back to 5.5 or so with a few drops of conc. sulphuric acid every 3 days when I did my top-ups.

This chart shows best pH ranges for soil and hydro but is lacking in data with the chopped off lines where absorption tapers off rather than begins and ends at a fixed point like the 2nd chart shows.

Some nutes are more easily absorbed at a much lower pH too. As long as you are between 5 - 7 the plants can get everything to some extent tho 5.5 is about the lowest I'd want to have a hydro tank stay at for any length of time.

This is why chasing pH is often a waste of time but some people are real OCD about it when it's not that huge a deal unless you are way out of range.
What’s the easiest way to clone?? I have purple punch and agent orange and wedding cake that I’d love to keep cloning. Just tried the rapid rooters in a dome with heat pad?? What should my nutes be???All right! Hydroponics is what I know, and hydroponics is the way I grow!
This forum will be great, we can discuss anything hydro. No dirtbags here, We haul water!
We can compare the different nutrient salts, and all of the additives. Plus the kinds of soilless media and what irrigation system is best for each. And of course, pH and TDS measuring equipment, feeding and flushing, etc.
And all the while, we'll make fun of those guys hauling big bags of dirt!
I can't think of any questions right now, what do YOU want to know?
Using pool shock?? Isn’t it I high dose of hydrogen peroxide?? And what’s the ratio please tell me. ThanksSudden drooping like that is generally from root rot cutting off the plants ability to get water. I'd be checking the roots again and looking for any dark areas in them. They don't always go slimy when they go bad. I think depends on the type of organism that is doing the rot and there are many.
Move your light further from the plant or dim it if that's an option and spray plain, preferably RO water, on the leaves getting the undersides good to keep the plant hydrated. If it looks like rot starting you'll need to dose it well with H2O2 or pool shock.
No nutes for cloning.
Pool shock is chlorine. I'm sure if you search you can find a whole thread on it here with all the answers about Pool Shock and cloning.Using pool shock?? Isn’t it I high dose of hydrogen peroxide?? And what’s the ratio please tell me. Thanks
I've only used 35% food grade peroxide so can't help you with the pool shock. Chlorine is unhealthy for plants or humans. 0.5ml/L twice a week for maintenance but 4ml/L daily for a few days to fight root rot. Then every 2nd day for a few more doses until you see healthy roots taking over. Remove any dead roots from the water or root balls before starting treatment. Generally best to do a nute change at 50 - 75% of what you had for nutes and no organics in there like beneficials or amino acids or the peroxide will be wasted destroying that stuff too.Using pool shock??

Thank you very much. But I’ve also heard not to use salt based nutes??I've only used 35% food grade peroxide so can't help you with the pool shock.

Lots of aeration too!
I'm of that thinking. Anything with sodium is a salt. Starts blocking nute uptake. Most chems I use are hydroxides. Careful when u play with them.
Want site some sources for this info? You know full well this is not accurate.....
There are thousands of salts that have no sodium. Hydroxides are alkaline salts where sodium hydroxide, (NaOH), is one and potassium hydroxide, (KOH) is another of many in the hydroxide family. All the minerals in most peoples tap water are in the form of salts. What about Epsom Salts, (Magnesium chloride or MgCl)?
Look it up yourself and find out you Failedmore.
Sodium hydroxide is not table salt. sodium chloride is.
FIFY. My bad. Still on my first coffee and not quite awake yet.
NO.... go back and read. I said anything with sodium is a salt I didn't say all salts must have sodium.
Retired Cranky chemist.
Everything is a carcinogen when taken in strong enough doses. Do you know why every human thinks fake sugar is a carcinogen...because they jammed 1000000% the dose in mice. Now people say fake sugar gives you cancer.
I didn't say anything about using chlorine is particularly bad for the plants but less chlorine in any environment is a good thing so I use peroxide instead of chlorine. Nothing but oxygen and water. It takes a lot less than 100000% of chlorine to be harmful to living things.
Patently false. Too much pure water can kill you but it won't give you cancer for one.
