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.
OK keep an eye on them those yellow leaves won’t recover. Can you raise your lights a couple of inches? Place the back of your hand under the light if it is to hot for your hand it is to hot for your plants.
