I was a little bit confused because I thought you should mix lime with the soil..
And you said you have added lime to the water.. Now I got you..
It's hydrated lime.. You should think about not using it..
I know it will be your quick solution to your current ph problem but you should just ph'd water little bit higher..
I read a thread on this issue and using hydrated lime is not recommended because it could burn your plant if you are not cautious.. I know this could be a personal opinion but.. I want you to take the safe road..
Anyway, I hope that it works out for you~
I went out and bought 2 boxes of dolomite lime.. no more f****** ph problems.. I say~ :thumbsup:
