[sootyaba]

Water is too cold would be my first guess, if that's good my guess would be cal-mag.

having some massive problems now. as soon as i PH the water to 5.8 within a cpl of hours the PH spikes to 7.0 im using AN micro grow and bloom.using tap water that has been stood for over 24 hours the water were i live has ppm under 100 starting to get the tell tale signs of PH problems on the leaves now and i cant keep up having to PH the water 6 or 7 times a day im thinking of throwing the towel in.the plants have been growing great and the roots are great on them and very white.HELP

Whats ur e.c. And got pics?

 

[sootyaba]

Ec when topped up is 1.0 and 7.0 at the minute it's due to be topped on monday

 

[Dusty Kiefers]

Hmmm can you discribe the leaves.

 

[sootyaba]

exactly like that those

 

[Dusty Kiefers]

Sorry, I cant see pics. A couple of things that make ph go up are underfeeding,root disswase, high rez temps. Check on those things and hope all grows well

 

[sootyaba]

would you say 0.9 is to low for EC?

 

[sootyaba]

The leaves have like copper colour patches on thm iv googled ph problems and the exact same images that look exactly like my leaves

 

[Dusty Kiefers]

some plants need more than others if every thing else looks good thats what I wo yould try

 

[sootyaba]

I'll yet that tomorrow thanx I'll let you know how I go on

 

[Dusty Kiefers]

Rust colored spots that arent crispy is cal deficiency. At .9 e.c. thats more than likly what your looking at

there are several reason why your pH would rise in your reservoir. most likely it is the calcium buffer in your source water that must be adjusted several times to remain stable, your plants may also be using more nutrients then water. when your pH sises what is your ppm reading and how much does it change? your leaf damage is most likely from a nutrient lockout caused by high pH.
