Being my first time I thought I overfed with nutes even though I reduced them being as I’m growing autos. I’ve since realized I was over watering and I’m not putting a water amount because I don’t have an exact amount. I was using a 2 gallon watering can for my girls but now I’ve since switched to a 2 gallon sprayer for more control. I spray until top soil is slightly over soaked and check daily with my finger down to about 2 inches for moisture in soil and water accordingly. I know this is my first time but I have a little help from a few with experience so it’s going better now :)
Don’t defoliate autos that late in flowering, you only risk stressing them unnecessarily. You are doing tremendous for a first timer! Keep the good work and dedication!
