You can raise PH with :
5.Dolomitic lime. flush soil with a teaspoon per gallon of water to raise pH.
6.Baking Soda. eats acids to raise pH.
7.Calcium carbonate. raises pH (very strong)
8.Potassium silicate. raises pH.
A good, organic compost like yours with some dolomite lime should buffer the PH and leave you worry free.
I don't worry too much about PH, my nutrient solution PH is 6.8 and the runoff is 6.4 making my soil 6 and the plants are doing well with some calmag added.
I used dolomite lime in my soil but it was the first time i'd used it and there were two things i didn't take into consideration.
Firstly, the lime needs time to integrate with the soil, a minimum of one month, my soil didn't get that time with three of my plants, but the soil for my fourth plant was sitting there for ttwo weeks longer (due to some failed seeds) and this plant is experiencing less intense calmag deficiency, so it's definitely worth mixing your compost a month before planting when using dolomite lime.
Secondly, i only put in one tbsp per 3 litres (3/4 of a gallon) of soil. I think i will double this next time.

Hey Steely thanks for all the infos bud..
It seems that i will be using some Dolomite lime next time, for now I m gonna crush some eggshells and poke a few hole to try and disperse it a bit better.
My water is Alkaline coming out of the tap at 7.5 and after a day getting the clorine out it raises to 7.7 usually.
I use distilled white vinegar as PH down and get to 6.6/6.5 before feeding. I might up this to 6.8 to try and raise the soil PH.
Baking soda seems interesting too!
I didn't realize that Bio Biz was organic,therefore you should not have any lockout and ph isn't that important.Also there is no salt build up with organic nutes and flushing is really not needed.Organic nutes do require cal/mag to work properly because it helps with the break down of organic matter so the roots can use it to feed the plants.Like I said before you need more of your macro nutes like nit,phos, and potassium.Your nutes should also contain micro nutes like iron,manganiese,zinc,nickel,and sulfur.
Hey Nam, the soil is way too wet for me to feed anything at moment, I might just foliar feed with a mild solution of Cal-mag,Fishmix (6-4-2), and some Algamic.
Biobizz seems pretty complete with an extensive ammount of different goodness in, so hopefully this will do in the mid time.
The sensizym should do some good as well.

ive never used bio bizz bat mix myself, has it already got buffers in it ? or do u have to modify the ph yourself? ive only used all mix which i dont ph and light mix which i ph to around 6.1. i dont exsperience any lockout really with organic nutes but i would still recommend flushing...
Hey man thanks for swinging by:tiphat:,
On my first grow try I used PLAGRON Bat mix and the stuff was way too hot for the ladies, one of them survived but is only 15cm high I kept it to see if it would bud which she has... I will harvest the smallest plant in a couple of weeks..
I am now using Biobizz light mix, which is way lighter and is supposed to buffer it self..
In this new media and in not even 10 days the 2 new ladies were bigger, greener, healthier..
Flush didn't seem to have bothered them one bit, overnight growth of 2-3 cm the leaves are still really pale..
22-24˚c and a RHof 65% :check:
