Fastbuds Afghan Kush Auto

Day 51 Had some N probs in the transition and pH probs that locked N SO, I did a cpl of very weak N foliar feeds (0.5ml GrowBig in 800ml) in the morning bottom leaf hour before lights came on, a week apart - leaves darkened up loads, N leach slowed down and buds started packing - all good. Think this is coz I have better ec in coir mix and also I let them go feral w no defoliation and wasn't prepared for speed of nute use
