Hello guys, I’m growing under 2 600 watts hps, Everything has been going super good. I’m growing rainbow wreck and wihite widows x big bud. Been flowering for 20 day’s and I found these deficiencies on my plants Can I know what they are deficient in
Whats your ph? What nutes are you using? Have a look at this. Why Cannabis Leaves Turn Yellow | Grow Weed Easy
I use Bio Bizz soil & nutes. I just realised I had the same problem with my last grow. It started in about the 2nd week, if I remember right. I tried adding epsom salts, had same ph as you. I never figured out what it was. According to a map of where I live Im in a very hard water area & I have a lot of cal/mag in my tap water, so guessing its not that deficiency?
