ph probs

[tigger]

i'm running a recirculating flood and drain and my ph needs to be lowered from approx 7.0, twice per day. seems like something is wrong, what is the best ph range for this system? i have been trying to kep it about 5.8-6.1

i have even found it rise to 7.4!

1st what are your nutes??

have you added anything else?

 

6.3 is ideal in flood and drain(ebb and flow), if your using inert medium like hydroton,

 

 

I found my system does that if i use crappy nutes, Since changine to Amsterdam indoors I havent had to touch mine, where normally i would adjust it everyday.

hi tigger

water straight outa the tap here today showed a ph of 7.5 must be this huge hole we live in figuring for a rise like that plants must be gettin big could do what i do n check (there fore adjust ) less as i under stand it the plants consumin the nutes causes the ph rise sure someone will correct me if im wrong if there packin it on wouldnt worry too much n only adjust once a day just my option anyways

hiya tigger....so have you adjusted the ph of the main barrell of water so you dont have to keep mucking around with your brain so much? ie adjusted the whole barrell of nute and water?

 

Are your plants adversely being affected by this ph? if not and they seem to be doing very well then why worry about this?

well the res was just tap water with a little superthrive. having run tap water for the first 10 days and using quarter of a bottle of ph down to keep things in order. i'ts not as bad now with nutes. so its normal to adjust the nutes once per day in this type setup? canna nutes btw

thanks for the replys
