I have a seedling around 3 inches tall, top of plant is healthy and green, but bottom leaves are starting to yellow and droop, it looks like it needs nitrogen. I just ordered Grow Big from Foxfarm. Is there anything else that can be used, while I'm waiting for the ferts?
If it is the very bottom leaves (water leaves) they will fall off after the plant grows a few more sets. Mine always do
Unless you're growing in sand, your soil will have all the nutes a 3 inch seedling would need. To me this means you're probably overwatering so try to let the soil dry out a bit see what happens.
yea i thought it might be the watering as well. one of the upper leaves is gettting brown spots now, would that still be the water?
