Stem and knobs

the difference in node spacing means your not hanging your light at the correct distance or you do not have the correct spectrum of light. tight internode spacing is key to a large harvest. more branches more bud its simple science lol

Nothing to worry about. Your lighting might be a little too strong will make the plant more short and condensed. Stretching is where the magic happens.

Revise su diario y la distancia de su lámpara es la correcta. Aveses para que su planta se estire un poco es cuestión de alejar la lámpara. También puedo pensar que su planta es predominancia indica y es una planta más ancha que larga. Se ve saludable. Saludos.

I think she looks healthy and what you are seeing is probably just a characteristic of Amnesia Lemon. Some strains have tight nodes and some have more space between. I’ve seen it all, but the main thing is she looks healthy. When the plant gets older they will spread out more and won’t be as tight. Hope this helps.
