Very round plant help!

one of my plants leaves are very droopy it almost looks like a round plant from side to side the others plants are all straight and normal.

I had drooping leaves, it was a case of overwatering. Give them a day or 2 to just soak up water. They should stiffen up. If thats not the case, Ive also heard root aphids possibly, or ph lockup. Not too sure, just noticed nobody had responded so I figured point you in some direction. Give them all a google.

round leaves cause ur ph is too high, and droopy leaves cause ur overwatering...unless ur underwatering. which i doubt ur doing
