I have a Northern Lights that is about 8.5 weeks. It is in a grow with an OG Kush and a White Widow. all are auto. I am using Nebula's nutrient guide for soil using GH nutes (Flora series). so far it is only the NL that is suffering from yellow tips across the whole plant.
The rest of the plant appears to be growing fine and there is no sign of pests but I can't figure out why it is the only one that has yellow tips on the entire plant, not just the top. The OG has some yellow tips but they are only at the top so I assumed it was light burn and moved the light up 4 inches (to 18" from top of plants).
all three autos get the same light, water and nutes and are in the same soil and fabric pots.
any ideas other than the obvious? Again it is only affecting the NL and only the tips of the leaves.
