It’s look a bit like phosphorus deficiency but I’m not quite sure and this is my first time ever growing a thing lol.. She’s a 4 week going on 5 week old West Cost OG by fastbuds. She is in a 3 gallon bucket with black gold natural and organic and been feeding her distilled water PhD to 6.5 and been adding calMAg. Just started using bloom nutes at 1/4th strength 2 days ago. My temps are 72-76 degrees Fahrenheit and around 50-56 percent RH.
