my water has an ec of 0.1 so im assuming i should add a little of this stuff. would a 1/4 dose (4 and a bit teaspoons in 70lt) at every res change, then just left, be enough to top up the mg already in the water. I've never seen major deficiencys but i always think my plants are needing something especially, like yours, when they're young. i cant be arsed changing my res more than once a week and really just looking for dose and forget sort of thing.
any thoughts?
