Cant seem to upload pics at the min , so i'll try and describe as bes as i can ,

First i noticed a little brown line on one of the bottom fan leaves , i was keeping me eye on it for a few days and now it looks like its rusting , but now it seems to have move up the plant mostly the fan leaves , some have rusty coloured dots but most have it in the centre of the leaves,. Also the stems are really going purple and leave are going dark green , I think the plant is really stressing now!!

MG ????? SHOULD I FLUSH ?? IF SO WHAT SHOULD I PH THE WATER AT AND WILL IT BE FINE TO USE IT STRAIGHT FROM THE TAP ,MAYBE MIX SOME HOT WATER TO BRING TEMP OF THE WATER UP ???

I'm not an expert in this area. After u post pics I'm sure someone will be able to help. Everything seems ok except that u foliage feed. Quit that. In nature when does god ever foliar feed? The plant has roots for a reason. I know when I water sometimes the lower leaves get wet and it turns them rusty. But like I said I'm no expert at solving others problems.

what and where is a troubleshooting form?? i've not seen anything like that. where do i go look for it??
