LED Strip Thermal Paste

Don't start playing the calmag game mate. Go buy some nice vermicompost and stir it in the top, then make a tea with a handful of the leftover VC. And water the coco to innoculate it.
I spend weeks chasing my tail with a PPM meter and calmag until I just listened to a horticulturist with experience of coco and cannabis. It does help starting out with good coco that is properly buffered and loaded.
I'm not chasing a cal-mag issue. I'm chasing an overall nutrient deficiency caused by the different nutrient demand of plants grown under LEDs instead of MH.
It's not the nutrients fault nor is it the LEDs fault and not the coirs fault.The only fault is that I have my nutrient profile set-up for how my plant performed under the environment they were given by me. I changed that by switching to LEDs.
And in my indoor coir grows I'm strictly synthetics. Dirt stays outside were it belongs.
And the plants are looking 100% better.

Just for a reference on my VPD.
This plant was switched from MH to the LEDs 3 days ago and I definitely see a cal and more than likely a mag diff. also.

And a plant with the problems switched to MH 3 days ago amongst her sisters under MH their entire life.

Do you have another sensor? Maybe the readings are too high? I've 3 temp/humidity sensors and one of 3 shows 20% less humidity as the other two. I would at least check that once.

I have several around. Including the one on the dehuie but I agree with you on the wide variable of readings from sensor to sensor.
As I said it's just the matter that I was using a nutrient profile set-up for my HIDs, which was borderline on being underfed as that's what I do to find the correct nutrient formula for my rooms.
