First feed and water, most turned upwards. Some had some curling. The leaves are also a lot bigger and lighter, than my other. Any ideas?

The upturned edges of some of your leaves are an indication it's a little warm and they are too close to the light.

Leaves being bigger don't matter. Leaves being light in color might matter. Are the leaves lighter in color than other leaves on the same plant? What part is lighter, what part is darker?

Light is 36" but powerful 600 w led. Only 1 strain is doing this and all of top growth.

They are darken.

It's a mobile nutrient problem. It might be Mg but it also might be P. The problem there is if it's P, adding Cal/Mag will make the problem worse. You're in fabric pots, so over watering might not be the issue. How about pH?

ASSUMING YOUR pH IS OK AND YOU'RE NOT OVER WATERING (a big assumption, either of those could be the problem): I would start with a nutrient high in P — most flower nutes should fit the bill. If that doesn't work, Cal/Mag.

@mysticepipedon has stated
Start with water ph
Then move on to other root causes until you can pin point your exact issue

Both are progressively getting darker, other than the deficiencies popping up. Some new growth but not anything that eases my mind. The girls are on their downward spiral.They have no nitrogen.

Nope

looks like the effects from being overwatered or nitrogen toxicity..
i haven’t read much of the thread.
how do you know when it’s time to water?

First time its been really wet. Its nitrogen, I think.
