Can anyone help out what's going on with these leaves. Medium is sunshine mix#4, 5gal bucket, 3part GH flora nutes, 1000watt hps.
Just started third week since12/12. I watered with half strength nutes afew days ago and started noticing these leaves around the middle. I was going to give plain water in a day or so when it dries but any ideas what's causing this??
