Thanks a lot weezard, here is a picture. This leaf was green and lovely two days ago, this is how it is now.




I've been told it was magnesium problem, so I put in some epsom salts and dolomite. I also added a layer of humus on top.

I'm thinking the best thing to do is to buy some good soil from a grow shop and put the plants in there, the problem is that theyre already in their last 7 L pots, wont the old soil stay in the roots?

Thank you so much
