I think you have overfertilize the plant ... it dosn`t look like defficency of pHTheyve been smelling a bit now for a few weeks, they started off like tomato plant smell and became more and more weedy, now they just have a nice mix of each, nothing too strong... yet!
A is having some problems thoSome of her leaves are going brown and patchy. Hoping its some sort of defficency or pH problem and not a disease. Hopefully getting some stuff to help pH and some nutes etc soon...
