Sick plant, any tips?

[Bskuzo]

so three of the plants are candy kush and one auto pounder I've been feeding them the lucas formula and the only sick one is the one candy kush (its the tallest plant, but aint producing shit) I've got them in coco and water everyday. They have Bout a month and a half left to go. Any tips to fix this sick plant

wow. That one may be lost. it looks extreme overwatering and a pH swing. But whether thats the culprit or not, you have some pretty severe wilting.

If you water your pot completely there should be no reason to water every day.If the pot is heavy when you lift it than there is no need to water,so skip watering a few days and see if this helps.

.... oh man, this girls is hurtin' for certain,... coco, daily feeding, right? (never water alone in coco, just confirming...), ....good drainage? It's very difficult to overwater in coco, provided the drainage is good,... No bad dry-out either? that can make pocket of dry medium,.... that said, when the entire plant goes limp like that, something bad has happened to the roots,... root aphids may be a cause,...
