Need help with brown spots on leafs

[tyler_ hobbyist]

Can someone tell me what this is and how to fix it?

[Sww]

Over feed plant feeling ill.

[tyler_ hobbyist]

Over feeding wouldn't that be nutrient burn with brown tips

[Sww]

No,, nuteburn is the nuts burning from heat, light. That's over feed like gutsy.dark green and one tip is curl down to much nitrogen and so. Overfed not nuteburn

I'm between a few things.

- overwatering,
- underwatering,

because of the droopy leaves. but you have a top-fed system....

- pH not in range (5.5 - 6.5)
- root zone issues
- possible calcium deficiency, though unlikely i think.

for the spots.

that red material the stem is in, how moist is that?
