Thanks for the PM regarding that bit I did there ********* you are quite right well done and yes good idea...!
Anyone like a quiz while we wait to see if weedz is taking my advice and he's doing the soil test? I have the answer and the pictures of my step by step solution to the problem, don't worry its simple enough to diagnose....! I don't want a solution I want to know whats caused it and how do I find out, it looks like a deficiency to me?
Whats wrong here chaps, whole plant effected from top to base. Barneys Blue Cheese 7 weeks in veg 1 week approximately 2 weeks in flower here. Soil grow with H&G Bat Special 50% large perlite, hand watered canna terra vega at 400ppm and Ph 6.2. 3 x 1000w air cooled hoods covering 1.7m x 3.5m.
