To be honest i was a little worried about the stretching at first but since then they've all tightened up and the nodes are only about an inch or less apart so whatever i did seems to have stopped that. A few are growing at angles too which is why i've added tape across the buckets to try and straighten them up and it's working fine, actually i've done away with all the tape now cos most are back to growing vertically.
