Hi GG,

For some reason my plant ('Phsyco Donkey' is the strain) doesn't like the frothy stuff and the leaves started becoming discoloured and blotchy. I put it down to 'bad' bacteria in the solution upsetting the roots. But I guess different strains can tolerate different enviromental factors. Since I have added more ventilation, the froth has gone and the plant is much happier. I never noticed the froth in my first grow, so knew it must be something to do with the environment, most likely temperature.

You must have a good hardy strain there, or mine is just a big softy!
