thanks for the reply invision.
iv tried the lime & the epsom salts & the plant still looks ill.
i disconected the feed tube & waited to see if its still feeding.
after 2 days,the level of feed hasnt moved at all.plant not taking feed.does this have anything to do with rootbound or do you have any other ideas.
look at the pics of what its growing in & you will see the feeding sysyem.the roots are growing out of the bottom holes in the pot & into the feed.i hope this helps more to a answer from anyone.
thanks
