can you show us the roots?Cheers, last time I did the bucket yes it was about 420 but then made a bit of a mess adjusting pH, pH up/down will raise ppm so it ended up at 480. A day later no change, pH up from 5.7 to 6.1 so put that back down to 5.6. The damage doesnt seem to be spreading and new growth is ok. Not the healthiest looking plant, she seems a bit pale, hopefully she starts feeding a bit more soon. And yeah will do a bit of work on the bucket try and tidy it up a bit make sure theres no light leeking in...cheers!
