EC or ppm? is the tip burn new or old? i like to drop my EC towards the last few weeks: they tend not to feed as much.

It’s new, I didn’t check ec but lowered my nutrients a little over a week ago, should I do a run off test to see where is at? What should the ec be around during the last week or two of flower?
i dont' check runoff in coco. i just try to make sure the pH and EC of what's going in is correct.

how many times a day do you feed? and always feed to runoff with coco.

if i was feeding at 1.0EC , i'd drop it to 0.6 or so for the last 2 weeks.

Yes always runoff but I only feed once every other day in 5 gal pots

Plant still has a good couple weeks left, if not little longer.
Might have cut nutrients a bit short.

Never really dips below about 1.8 - 2.0 EC for me. From veg to flower.
Though truthfully, the last several days to a week, I just give them water.
That's out of pure lazyness and plants are so close by then, it doesn't matter anyway.
But that's me, others feed less, some more.
I wouldn't ever take it over 2.0 EC to be safe.

In future you might find it better, to feed once daily, as a minimum.
Add some perlite if you think it needs more aeration or drainage in larger pots.
Though straight coco's generally alright on it's own.
should I do a run off test to see where is at?
Only if it's to rule out high EC in the media. Best it ever is, is an indication too. Otherwise unreliable.
I would just take it easy. Keep feeding nutrient to runoff. Ride it out, chalk it up for next-time.
About 1.2 EC would be my minimum input, personally.
With good drainage and aeration, which coco has, you should be able to follow manufacturer's feeding chart, for inert media, or DTW garden.
It's when coco starts to dry often, that becomes a problem, coco's a big sponge.
Performs better with once daily, to multiple irrigations per day.

You're doing what I call "lazy watering". As stated, coco needs DAILY fertigation or these are the problems that'll arise.

Get back to a daily watering schedule. Keep in mind COCO IS NOT DIRT, DO NOT LET IT DRY OUT, that's like letting a DWC reservoir go dry, which is no bueno.

And, there's a few white speckles here and there, on the leaves, some out of focus on lower leaves.
What are they?
Have you had any thrips or anything?
Probably just my eyes and the photo.
