The problem there is almost definitely the ph. You need to raise it higher, why can’t you raise it? That looks like a calcium deficiency and maybe some ph spotting too due to the low ph. You really need to get that ph up to 6.2-6.7 ish

You need to add some lime to your soil. You should stay with veg nutes until flowers form. Best to go into flower with a healthy plant. Cheers

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.
