Touchwood it has improved today slightly.

Did you add some cal-mag or something? It was a really small issue so, easily fixable.

I aint done anything accept raise light height and lower the output

@Ryandep6, I’m still hung up on your extended periods between watering/feeding in straight coco. Maybe I’m missing something. In any event, I’ll toss out this link that addresses watering when growing in coco. For what it’s worth….

HOW TO WATER COCO FOR BEST RESULTS.

Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...

Do we know why LEDs tend to give plants this problem?

I do not. I'm not sure anyone knows. I've followed more than a few discussions about it, but have yet to see an answer. My guess it has something to do with the light spectrum LEDs emit. Lowering the light intensity is known to help. Maybe increasing the distance would, too. Changing the light is the quickest fix, but increasing the Mg works too. I think most growers change the light and add Mg, and then slowly raise the lights as the plants can tolerate the increase.

And is Epsom salts the best thing to add?

Many soil growers use it, including me. It certainly isn't the only source. I think Epsom Salts are commonly used because they're inexpensive and readily available. Cal-Mag has Mg, but Ca, too, and increasing the Ca may not be necessary.

Is there something better?

Not to my knowledge. Epsom Salts can be mixed with water, top dressed or foliar fed to the plants.

You physically checked with a scope?

A lot of deficiencies are caused from bugs,
The pictures above are of your plant pics,
What I circled could possibly be a bug,
Thrips love to travel and feed on top of the leaves,
They can be seen from the naked eye in most cases.
Spider mites are under the leaves and stay there and breed until the colony is established.

Cool, I didn't know any of that, thank you. So what do I do with the Gypsum I have? I'm afraid to foliar feed.......I'll just get the floor and walls wet, and then have to spray the residue off......I'll have iron claw hands from squeezing the spray bottle, but

Maybe something LEDs do, or don't do, that's different from the sun.......that accounts for the deficiencies

I have checked wht you see is coco fibre from fan blowing when its dried slightly

This chart may be helpful in the future

Awesome advice. I use a similar chart . Mine shows a single leaf w all the deficiency remedy.
