5th Week Flowering Plant dying!

Start by just giving plain water, nothing else and then harvest in 10 days or so. Nothing can be done now to fix these problem.

So. This is simple. The answers and folks you been listening to got you here. Plant has too much nitrogen, and not enough potassium and phosphorus. Likely but not necessarily causing a ph imbalance as well in your soil.

The problem doesn't seem to be caused by a deficiency. The nutrients are present in the substrate but cannot be processed or absorbed. There's a blockage. With harvest just around the corner, maybe it would be worth considering flushing the plants?
