Yellowing of leaves. These are 6 week old autos. Been watering every 3 days to about 20% runoff. Been in flower for about 2 weeks. First im seeing of this
That looks like normal shedding. The plant is done with those leaves and has drained them of nutrients. They are starting to flower so now would be a good time to increase the Phosphorous and Potassium (P+K) when feeding.
You should also check ppms + ph of your water / soil just to be safe
Just uneven coloring I suspect. Common on seedlings.
