I'm running DWC in 5 gallon buckets and I added 95ML of H202 3% to 3 gallons of water with nutes and in about 15 minutes they pretty much laid down and died it appeared but they got back up and now the leaves are burnt and droopy and they dont appear to be growing. I flushed each bucket and they have just fresh ph water in them I'm thinking of flushing for 2-3 days then start back with nutes.
