Hi, Can anyone tell me what is the best way to test PH levels in water and soil, I think my water from the tap is around 7.5 after doing a little research, I know the ideal PH levels should be around 5.0-6.5. what can I use to test he soil PH levels also, as I am guessing the tap water I have been using increases the PH level in soil also. Is it best to use things like litmus paper you can buy from pharmacy or a electronic reader. If PH levels are to high what is the best way to lower PH levels to an acceptable standard. and will PH levels of 7.55 do harm to the plants if I carry on. I am growing outdoors in 11l pots in plant magic supreme soil. hoping that rain water, when it rains lowers PH levels in the soil from the tap water. I am currently feeding plant magic soil grow, mixed in tap water.1.7ml/0.75L recommendation is 2ml-4ml/1L Once per week, I am noticing slight leaf curl also and tips of leaves yellowing. Might be due to nute lock as PH levels to high or nitrogen toxicity. Please help
