Nice one. Just completed 1 hour flush cycle. Run off was 0.9 so fair bit of salts removed I guess. Now draining that to waste before adding fresh water for a night of flushes. Will then get to work with a fresh res and h2o2 tomorrow as its ordered already. I'll also look at those alternatives, thanks

So, daily update as I'm now quite enjoying this forum. And maybe the thread could be helpful to another noob like me one day.
Second flush was left to run on the normal flood and drain cycle last night. This evening the res was reading 0.5 EC. I've dumped that water, refilled with plain tap water with 0.8ml per litre of the 12% h2o2 (actually slightly below the instructed amount on the bottle, but I've aimed conservative). After 30 mins circulating that water read 0.3 EC. I've now dumped that and am doing one more fresh flush cycle of 20 mins (plain water plus h202).
The plan from here is to drain that res. Then refill with a lighter feed (about 1.2 EC) a touch of calmag and 0.4ml/litre of h2o2. I'm then going to have to leave it for 3 days and hope for the best. Mrs birthday tomorrow and I've agreed to take her out, followed by a weekend away at her friends. If there's anything blatantly stupid in this plan please do chip in.
Since yesterday the leaf damage has increased very marginally, but I know things happen quickly in hydro and I feel like I'm making progress here. Buds still looking lovely so I'm optimistic of a decent harvest in a few weeks time.

Time for another update. Checked res again on Sunday. Ph and EC had remained stable for 3 days, water level dropped reasonably. Topped up h202.
Have this evening changed out res again. 1.2ec including a small amount of calmag again and the h2o2 treatment. Plants still looking a bit stressed. Leaf damage is progressing and spreading across the garden, although quite slowly now. I've added some more pics.
Just wondering if there's anything else I can do to help them now? Will be 7 weeks in flower tomorrow. Was hoping to run till about 10. Buds still look ok at the moment but I'm worried this issue might start effecting them too.
