Low plants

plants can remain low for a number of reasons : the light was too close, genetics, not enough veg, shock, training etc. but i think what happened here is to do with the soil, sometimes if you water without being super careful and slow about it you compact the earth and the roots have trouble stretching out so the plant remains small. Nothing you can do about it now, but for next grow try what i do : keep you soil medium really fluffy and water very little by little being extra careful not to compact the soil in any way. you'd be surprised what a huge difference that makes. hope this helps ! 🚀
