Thanks bid. I'm in hydro - NFT. I'm thinking possibly I've kept my ph too low for a few weeks (mid 5s) - I find it hard to tell what it is sometimes using the drops as the tank solution is brown / yellow before I even do the test. I've picked up a ph pen now so hopefully will be better able to measure it. The other thing I was thinking was that possibly the strain is less receptive to defol as it's a sativa dominant I believe and early on in this thread there was mention that indicas responded best.
