Spindly thin tops

I supercropped them so the tops are down like 8 inches parallel with the other two main colas on the side from the bottoms.If it don’t do that anymore and only starts to do this Oliver Twist bullshit when it gets taller to the light then I think I’m going to have to either try and hike it up 6 more inches or run it dim on 15 percent for a bit.Plants are around a month and a half old.
