Issues after switching to LED lights

Okay, couldn't find any info on that particular brand of coco but let's assume it is washed and buffered ?
If it doesn't say it's buffered you may have to add Cal/Mag, at least at the beginning and preferably before starting a seed or transplant.
Then your nutrient brand should take over (check to see it contains Cal/Mag).
Maybe a watering issue ? Coco likes to be wetter than soilless...
Lift the pot and if it feels light you've waited too long to water.
Coco also likes a bit of run off. What I do is water to run off and pick the pot up. Do that until it feels like a little less than half, then water. Some just water coco to run off everyday ! Even multiple times
Rest assured it is not the light. That model does have a hot spot in the center But the outside edges still provide plenty of light for a successful grow !
Light is @30% but at what height ?
FYI > to fine tune the optimal amount of light for your plant you can download a free lux meter app. Then take a reading at plant top height and use the conversion factor of .015 to get a par value.
At 7 weeks I'm at 600 par @ 17".
There's lots of lists of optimal par values per stage of growth out there.....
Feed is the last thing I can think of, for now
I've tried three different nutrient brands and all of them got me into trouble at anything over 1000 ppm.
Right now at a week into 12/12 I'm feeding 640 ppm..
Hope you get it figured out, eh ?
Cheers
Hello, LEDs are a great thing and the developments are a blessing for us. As long as they aren't bad Chinese firecrackers. A lot of what you have already been told is correct.
As we progress, we tend to lose our footing.
Basis: PH value germination cloning cultivation PH 5.8 .... 5.6-5.8 Depending on the variety. 5.8 is most good depending on the protocol.
You grow on soil! Set the pH value to 6.1...5.8-7.2 depending on the sorter and protocol, but 6.1 is usually good.
A little tip on the side: many varieties have long been bred with quite high zinc levels. New pipes are made of PP pipes (polypropylene) or PVC pipes. Put a few galvanized nails or screws into the ground if that's your case.
