Hey sis ,
When my beans are in r/w and not in buckets yet I add 2-3 drops of ea. Micro-Grow-Bloom and cal-mag , I don't have the luxury of R.O water yet . I p/h the gal. of mix though . I honestly have no idea as far as ppm. - our water is 80ppm. right from the tap though and w/ just a cpl. drops of ea. I dont see ppm. being over 150 .

Are the plants / cubes in the w/f yet ?

I dont put r/w cubes in w/f -buckets until they have atleast 4 nodes on them , till this happens we keep em in lil stooufers mac-n- cheese containers w/ just enough of said mix to cover the bottom of the container so r/w can wick up the mix as needed .

The 2 new indica strains I started in soil are doing great , but 2 sativas Im trying to get to grow are really starting to make me mad too .

Keep us posted
