YAsoob - sounds greek..
There is really nothing wrong with distilled water.. it is VERY safe..
BUT!!!!!!! there is nothing in it.. it is probably PH 7.0 with ZERO PPM
This can basically stop a plant from growing.. It will just kinda freeze in time.. and then slowly DIE. very slowly...
SOOOOO..
What kind of soil are you using? WHat brand? Do you know the starting PH of your soil...?
Are you flowering NOW..
If your plants are 2 months old.. you should be flowering NOW? correct?
