HELP! Slow new growth, light green

[Daquack]

Gg #4 Autoflower, Dwc, LED, GH Flora, hydrogaurd, PPM 400, PH 5.8-6.1, week 6

Had a case of root rot around week three that I was able to clear up. Both of the gorilla glue plants never seem to quite bounce back from it. The new growth is light green towards the middle of the leaf and gets darker towards the edge. New growth is slow, but the fan leaves seem to be growing. Have some rust colored spots on the big fan leaves, probably from the earlier root rot. Thought maybe it was a calcium deficiency? Upped my Cal Maga little bit, no change. They’re getting ready to Start flower , but there’s very little new growth.

Any help appreciated!

I gave up on a stubborn case of root rot and transferred to coco once. Plant really took off.

What is your bucket temp?

Always 68-70

I think I have the route right under control. It’s just the plant is still exhibiting signs of some kind a deficiency, and I can’t figure it out

Sometimes it's lighting to close also will make yellowing my 2 cents
