I would agree I would maybe start using just water. Or very very light nutes.

Your plants look very nice though. Nice lush green. they will yellow right up when you start giving them just water, But thats ok.

My plant has been in flower now for almost 10 weeks. It looks like asss.,. But I haven't feed it for three weeks or so. It should be ready to be chopped any day now. At least the main cola.

Those plants look nice. To be honest though they look like they will go a few weeks still. But thats justa guess from a not to experienced Grower.
