Rocket your right with the damp cold soil causing nute lock out, it happens and theres pretty much fuck all we can do about it apart from pray for better weather.
Thats it JGP... this May is colder than last year's thats for sure... im hoping that there will be a mini heat wave come July/Aug like last year just to help them gain a bit of weight.
Im not expecting monsters this year or any year for that matter TBH... if this were 20-30 years ago our harvests would have been very reasonable but the summers now are just too erratic to plan ahead .
