heh yeah bro, I've added some malt vinegar in with todays water to try and get the PH below 7.0 6.6, 6.8 I will be happy with, so I added 3-5ml of malt vinegar to approx 2 litres water+fert.

my PH tester shows a more orangey yellow, will be interesting to see how it affects the plants next week, I will keep adding vinegar if the PH keeps going to 7.

Peace,
Denial
