Robertsanswered grow question 4 years ago Autos are light feeders. Future grows use fabric smart bags and more perlite or growstone. Never leave plants sitting in run off water test ph and tds then toss. To help aerate the soil now you can add a 1 to 1 ratio of 3 percent hydrogen peroxide and water. DO NOT get on leaves. Will cook them. Roots will be totally fine. As h2o2 breaks down it produces air the roots need to breath under the soil. Will also kill bacteria that is involved with root rot. Good luck and happy growing
