Hi stinkyattic,

Here's a picture of one of the plants 4 days ago which would appear to show signs of a Mg def as well. I've been away for a few days so I gave them a good drink to keep them going, the heating was also turned down. Looking at the 4 day ago picture it looks like I already had a problem so I can rule out anything I've done recently. I have one of my old Skunk seeds going at the same time (yes the same strain that Hemied on me) and that looks fine, if not a lot smaller, so I can only assume that the GWS is a bit more particular of growing conditions. I'll have to get a Ph tester and check out the soil.
