Just looked through your first biotab attempt!
It's amazing how similar our results were ... almost to the day with the calmag def .. and then the crisping turning leaves.
I understand that a weekly innoculation (i'd need to double check this to be certain - not fully up with the organic guys) of one of their powders will help combat this... and the PK juice is to fatten and firm up the buds.
But year.. Day 40 calmag problem ... day 50-55, manked leaves!
I'll be (hopefully) getting it better this next time round!
