Lock out

Was wondering if I having lockout issues or what's goin on

Looks like poor feeding habits with dry coco around the edge? A plant that size should be soaked daily with a proper ph/ec nutrient solution with good run off.

To reset it flush it with a low EC solution for a couple days then resume with proper feeds daily

By the looks of it it’ll get worse, before it gets better. Should start seeing a change within a week imo.

Those pots need thoroughly watered with plenty of runoff in coco
