thankyou again, everyones been heaps of help. I pretty much rushed into a system that i probs shouldnt have used for this. Im considering alternatives for my next grow in a few weeks. The system i got is pretty much an auto hempy bucket right ? Anyways im using full strenght nutes now with a ph of 6.2, so im pretty much running everything just as the hempy-buckets guy has said in that thread.

I do think it is the nutes because it happened around the time i went from full strenght vega to 1/3 strenght flora. I probably shouldnt have done that but its all experience now.

Peace
