Hi All. I am a beginner in need of expert advice
So these girls are autos in their 2nd week of flower. I’m feeding them GH Gro nutes @ 50% strength on a 18 6 light cycle. Temp @ 77f and humidity at 60 %. These are under 400w quantum board.
Need help of what this issue is? Is this nute burn, light burn, nitrogen deficiency or something else.
Any indication of what this is ? Please help.
