Blue Gelato & Marmalade first coco grow

Just starting week 6 of flower. So added some overdrive. They are fattening up nice . Blue gelato is showing hints of purple too. Only thing is seeing some slight deficiencies on leaves not sure if its due to changing extractor from a 10 inch to a 6 or maybe ive hit them with a solution with a EC between 2.2/2.0 . So now keeping EC between 1.6/1.8 and trying to keep temps down.
