ive gone back to basics, i only add rhiztonic which is only for the first 3 weeks, to make more roots which seems to work really well for me.
the roots dont smell and the plants look pretty much perfect at the moment.
like i say its just so weird to do something for all that time then it change to the opposite, i grow in a nft system with the tank heated to 20c.
which way does anyone elses ph go who grows in a nft system. up or down.
