Its been a decade since my last grow. Forgot I needed to do a flush once a month for my flood and drain in coco. There must've been nutrient build up near the top of the medium. Here they are. Tell me what you guys think.

Im growing in Coco.ph is 5.8 and runoff seems to be about at 6.0. This is my first run with this strain so I'm not sure how much longer Ive got.

Don’t give them just water in coco.
You’ll fuck up the CEC of the coco and quickly get more problems.
If you think you’re running hot then back off your nutes 50%.
Personally I think you’re doing great for having a decade away.
Are you recycling your return water after flooding as I’ve found with coco a recirculating system can cause a few problems.

Yes I am recycling the water. Last week Ive dialed PPMs in half.

Just be aware that when growing on coco the return water isn’t necessarily going to contain an even mix of all nutrients required for next feeding and you may get really low pH or really high pH readings depending upon how the plants are extracting what they need.
Coco in itself needs high K just to sustain its CEC capacity.
Personally I always throw my coco return water onto my garden outside rather than reuse it on my girls.
