The plant is about 2.5-3 weeks old and have ran into its first problem. I have no idea why the lower leaves are already begging to turn yellow, I've been paying very close attention with how much light and water I've been giving her and she has been fine up until yesterday. Any guidance would help as this is my first grow after I moved north & have not grown in a bit. Please help me asap! Pictures will be attached Sent from my iPhone using Grasscity Forum
Need to feed? Yellowing because it's cannibalising the lower leaves for nitrogen uptake. Or bit less likely but PH in medium is off so it's not able to get the N from medium.
