can anyone help?

I have a pineapple express auto it looks like its suffering from 'the claw'(nitrogen toxicity) but the run off ph is in 6.6 - 6.7 range, I was thinking if it was over ferting the ph would come off at around 4.0 - 5.0 and I would also have burnt tips on the leaves would correcting the ph to 5.8 - 6.0 fix the problem? If so how would I go about lowering the ph of my medium? I've been watering with 5.0 - 5.5 ph the last few waterings to try and lower the ph but its not budging I'm using canna coco coir btw, any help will be much appreciated and I will put a picture on soon as the lights go out later on if needed.

I wouldn't try to correct your runoff pH by lowering your water pH. Continue to water with pH around 5.8 and back off your nutrients.

How often are you watering?

Flush the coco with 2-3 times the volume of the coco. But testing coco runoff is not the true ph of the coco. A slurry test is alto more accurate.
do not lower ph to try to correct it, you are doing alot more damage then good. Keep at 5.8. flush coco first

does it matter if I flush the coco tomorrow even though I just waterd today or will that start more problems?

Flush as soon as possible. As long as your drainage is good and your coco isn't packed too tight it's not going to saturate.

I water every 3 days because the coco takes forever to dry out and it stays wet however the pot does feel considerably lighter before I water again and I read that you cant overwater coco and watering once a day will bring oxygen to the root zone but that might be a factor to the ph problem (not letting top inch of coco dry before waterings).

I water ~3 times a day. You don't want your coco to dry out. Keep it moist, oxygenated, and fed. Water and least once a day until you see runoff.

I'm not an expert on flushing, never had to do it. I would think flush with pH'd water first and then water with nutrient water until you see a decent amount of runoff. That way you aren't wasting your nutrients. You might want to do a "how to flush coco" search though to get a second opinion.
