I think the mother plants the clones came from were already suffering from lack of ca and mg so from the start things were not ideal. yesterday I sprayed them with a mild solution of calcium ang already today they look healthier. I'm going to follow up with a mild solution of mg in a few days and see how things go. I'll post some more pics then.
I'm going to see how it works out with the additional Ca/Mg and decide weather I realy need to change to RO water.
thank you all for your advice...keep it coming...
