I would make a feed a bit lower than usual strength. Pour it through the pots so you get some run off. Tell us the EC and PH of the nutrients solution before it goes through the pot and the EC and PH of the run off that comes out of the pot. Just collect the first 40 mls or so and test that. From that we'll be able to tell you a bit more what's going on inside your pot. But yea it' looks like nute burn to me in which case giving it a bit of a flush with lower strength nutes would help.

Nice setup CDB, I will be tagging along for this one. I also grow in Plagron grow mix and I haven't seen nute burn like that. I sometimes saw slight browning of the tip of a leaf here and there but perhaps your soil is a bit hotter. I started feeding them in the beginning of week 4 at 1/4 strength. I didn't see any cal-mag in your list of nutrients you might need some later on.
Hehe, I had the same problem. I bought some Botanicare cal mag plus from Amazon in germany but it was shipped from the US anyway. The drawback is that it's pretty expensive and it took nearly a month to arrive. Another option might be to order Plant magic magne cal from the UK.
