Leaf Drying and Dying

[dwyndorf]

Hello,

 

One of my plants has started to develop yellow blotches on its leaves, after a few days these blotches turn into dry spots and the leaf becomes very brittle. I'm doing a SOG and the plant in question doesn't receive as much light as the others, could lack of light be the problem?

 

Cheers

is a site that relates to nutrients problems, its actually a Canna manual.

 

Take a look at the calcium one, and the magnesium one, Phosphorus one.

as they all have some sort of spots on them, hope it helps.

Thanks guys, it looks like a magnesium deficiency. The weird thing is; its only in one plant that shares a DWC tub (and Canna Vega nutrients) with three other healthy plants. I'm only in the third week of veg so I put it down to underfertilizing because I was only using 1/4 strength nutrients. I've just given them full strength, we will see what happens...

 

If anyone has any other ideas I'd love to hear them.

epsom salts work good for magnesium def.
