Hi guys just a quick question...I am slightly puzzled as to why the run off out of my pots is reading PH 5.5.. The feed I give is always around 6.2-6.5 PH... Any comments for me will be greatly appreciated and thanks in advance
New Grower Checking PH on Run Off in soil.....why 5.5???????????????

what kind of feed is it??
it seems a little caution heavy
a larger root mass in a smaller container will increase the acidic levels as amount of roots grown takes over the ratios of buffer and tip the scales because roots give off acidic change during lights on and heavy exchange is going on
you need to bump up the availability of adding some cal mag will help this
but you need to increase your buffering ability
adding some hummics will increase the exchange capacity before exhausting also
but it is probably from nitrogen or type of mix of nitrogen used and ratios in nutrient
you can increase the pk of some feeds and it will help this as well depending on the source
I would also add a little lime for extended buffering and prolonged slower exchange rate
but there is a little of the direction you asked hope this helps
in the shortest form you have too many + hydrogen atoms running around and you need some more hydroxide atoms to exchange and balance out your ratios

Warriors come out to play yay !!!!!!!!! three Heineken bottles clanking !.............Sirus........sorry warrior it just reminded me of the film "Warriors"...........1979?/...................
Yea, soil............1st you didant say how old the plant is ??......................second how much hyrdo your watering each day at what EC >>??....................
best advice if regs/fem-regs or auto's especially auto's under led power,...................add 1 to 2 teaspoons 5ml of granular Epsom salts and potash to your soil mix "Per/L" of soil, when blending in perlite and sand at 10% each warrior. This will buffer the soil at source and balance acidity etc..............as smurfs buffering advice is correct.....................my advice is measuring run of wont tell you a great deal warrior it dosent work like DWC EC/PH....make sure your tap water is well oxygenated before use. Add cal/mag buffers if used, to fresh aerated res water and leave to settle ph for 24hrs before adding nutes & root stims ok..........hope this helps.................good luck with finishing the grow............and next grow !!...............AB...............
