Hi. I have two auto blueberry and twp auto blackberry Kush which r 7weeks old. They should fo for another three weeks but around 10% of the pistils r dying already n the buds are no where near fat enough. Y is this? I have a 1.2m tent 600w light, intake and out take fans n good growing conditions but they was on 18/6 for first 5weeks n now 12/12 coz I'm flowering photo blue widows in same tent. Anyone know if I should b worring?
