Right, just flushed one, im terrible with any form of measurement i apologies, i know the pots are 14cm but im not sure how this equates across, flushed one plant with 1l of water, runoff is now 7.0 with waters ph being 7.6 still, this should be much better.. Right? Haha sorry for all the questions guys, it has been a long ass day!
