I have no way of getting cal mag down were I live , so will it help to maybe use some tap water mixed with RO water to help a bit .
Also , do you recommend transplanting the plants to another pot , they have been in these for 4 weeks more or less.

If my PH in my medium is 5.7 I should have my solution be a bit higher to get the medium to raise , I will try my solution at 6.5 to see what happens next watering.

Thanks Stinky again.
