Issues after switching to LED lights

In a potting mix Bloome & Gardener coco and perlite. Light is Mars Hydro FC 3000 its at about 30%. Don't know what par is at.

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

Yup, not happy, sigh...

Check the values I suggested and get back to us...

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.
