What is your temp and humidity? Low humidity will give you alllll sorts of fuckery, and have you chasing deficiencies and seeing rust, burnt tips and drooping etc.

i see dry pots and no pearlite or airation in the soil/coco

 

[Liamp1603]

I’ve never added perlite or anything for aeration into my coco and my temps are steady and humidity is steady

You probably need to water more often. I don’t grow in Hydroponic Coco but I do do organic coco. When it gets to dry you’ll have all sorts of problems.
Especially since you got higher temps and low Rh.

Calmag? The coco should never be dry.Your watering to runoff?

I thought I’ve been battling overwatering so I haven’t watered for a few days hence dry tops but it is still wet inside the pot a few inches down ?

Why no perlite? Makes it harder for feeding, so keep the ppms down until they can drink most of it in one day.

It’s pretty hard to overwater in coco so that may be your problem is letting it dry out to much. For coco I find that having it it somewhat moist is best.

Youll need a tray to hold all your pots,runoff from all your plants will soon be alot to manage.

Please read up more on coco, it should be very hard to overwater coco (especially with perlite added). As coco dries out it starts to release salts from within itself and this changes the EC of your medium and then your plants have to adjust how they suck up nutrients because roots operate on EC. So you want to keep it wet or its like constantly sucking the bottom of milkshake with a straw. These salts could also be the reason for your end tip burn

Feed today with lots of runoff,collect the first drippings and check the ph and ppm Report back.

Run off ppm are a little bit lower than going in at 748 and went in around 772 and ph is from 6.4 to 5.9
