Spiral Cactus Help Anyone know my spiral Cactus is light/ yellow in the middle? It was under a grow light (my house is dark inside) for months (Dec to mid-May) but I've recently moved him outside where he can get full sun. It has been rainy a lot recently though, so maybe it's gotten too much water... His base doesn't look rotted and the center isn't squishy; just yellow. Too little light initially? I'm tired of killing cactuses and succulents 😓 Originally by u/molynn86 on Reddit: https://tinyurl.com/2c3azc5j
