Problems:
-Pot too deep. Air flow around base of plant and at soil surface will be restricted. Low branches will suffocate. You have to plant the plant so that the soil surface is near the rim of the pot.
-Backyard dirt... not good... you need REAL potting soil indoors, with perlite.
-Yes you need more lights.
-TIMER!!! Just turning lights on and off by hand is guaranteed herms. You WILL forget.
-Why did you bring it inside? It looks like it was growing fine! I'd stick it back outdoors in a better location with some rich compost worked into the soil.
