Strange Twisting Leaves
I have a plant that's just over 3 weeks old, and since the first week or so, I noticed it has some leaves that grow with a "kink" or "twist." They all seem to have a small discolored spot on the edge of the leaf that eventually becomes the corner of the kink/twist

A deficiency, a toxicity and a toxic-deficiency???
Here's what I make of it (and PLEASE correct me where I am wrong!) : The tips yellowing indicates, a nitrogen burn. The burnt brown tip indicates, nitrogen burned to long 😂 The black spots indicate, a P or K issue (as the leaves are otherwise healthy green in color)

Brown/burnt spots on 1 plant only
Hello, D49 (out of 70 theoritically) same strain, same nutes but only one plant looks affected (top right). Looks like it started 2 or 3 days ago. Could it be nute burns ou some kind of lockout? If yes should I flush or could i only give tap water for a few waterings?
