hey guys, got some very sick plants! They are Pineapple Express from barneys farm grown in ecothrive coco fed advanced nutrients in a autopot system. I hadn't checked them in a week or so as been so busy. Just checked in on them and buds are looking ok but nearly all the leaves look bad!
Should I flush with straight water or would using canna flush help? Was going to give them a couple more weeks. The ec of the water/feed is 1.3 so shouldn't be have thought that would burn them? A glueberry og plant in a smaller pot that has had the same feed is completely fine.

-- we need some more normal light pics, whole plant included,.. where the symptoms hit is a big clue, as well as the appearance of the symptoms,... I think this looks to be mainly uppers affected? ... right now, I'm leaning toward P defc., from the looks of the necrotic spots and the buds themselves,... P defc. can get a little weird sometimes in it's manifestations,.. it is an mobile nutrient within the plant, but I'm finding that it's isn't necessarily being drawn up from lowers first, like Mg defc. usually does,... it can hit higher up... So let's see what new pics can resolve first,.. but I'd look into a PK booster....
ha! Oh yes, that cold spell can cause some troubles,... poor uptake all around when that cold, and P is one that lags out bad, as do some micronutes like Fe, Zn, Mn, etc.,... makes for odd symptoms sometimes,... 24/0 is OK for auto's, so that's not it,... what are the T and RH% in there currently? ... if you have coco specific nutes, then skip he extra Ca-Mg,... Autopots are an excellent system mate, but as with any such system, there's a learning curve,.. we have a killer Autopot section here, where you can find tons of info and help from other users,....
