Looks like you have overwatered the plant, maybe also incorrect pH

Over watering, too much nitrogen (curl), and possible micro nutrient deficiency or lock out. PH?

Reddening of leaves quite prevelent at top of plant. Think it might be a PK deficiency. Question being - is it too late to add a PK booster at this stage of flowering? [Or will I have to ride it out?] Thanks, Harry

Pineapple auto in soil tiny brown spot
My pineapple express auto is well into flower but the leaves look sick with light green patches and tiny brown spots appearing on some of the top leaves. The brown spots dont rub off on finger so don't think it's fungus. Not sure what I should do, it's getting flower nutes.

Black tips and spots on the leaves
I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves

Crumpled new growth?
I've noticed that there are new leaves towards the base of the plant that are growing strangely. Could this be from low humidity? I've been having a hard time keeping it up. I also noticed that some of the leaves are clawing down (see week pics). Perhaps related? Haven't fed yet!
