OK here it goes..exactly what davillains says, but guessing from looking at one leaf, you have N toxicity and they have locked out cal/mag, but before treating it for this id sure like a look at the whole plant and know what you have done. here is what a healthy plant looks like 8weeks into vegView attachment 3928744

Probably lol but let's hope it better than it looks.. I wasn't even sure I was going to smoke this anyways... But we'll see..I'd bet that bud is gonna taste like ass. I'd give her water only. I've been wrong before though.
Got any ideas now?hello, you need to provide some information like soil, nutrients/feeding schedule, temperature/humidity etc and pictures of the whole plant + closeups of problem under white light.... otherwise I don't see anyone bothering with this.
