Dark leaves and short/compact plant

I think the manure was too much. Definitely too much nitrogen as the leaves are shiny and very green. You wouldn’t think a lower wattage light could be too much and it’s not really BUT it’s keeping the plant very short and node spacing too tight because it’s too content and not moving up for light. I’d transplant it to new pot (bigger) lay off nitrogen and move that light up some. Good luck
