Hahaha you just threw up all the charts i have here haha. As you can imagine tho with out a solid ph tester its hard to maintain. I no from past exp that 2litres of over night tap water has a ph of 8.5..nuts huh lol, london water for ya. I add 0.5ml to 2litres of water to bring down to seven then add my nuts which gets me to the magic number. BUT!! If there is any fluctuation in the water. Age of nuts then i only have a test tube,ph indicator and my trusty soil probe. Would you say they look ok ? (apart from the ovious leaf burn you can see as i mentioned before. The pics are off my phone so dont no if there any goodd
