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?

Is this heat light burn? HPS 600w at 20cm
Is this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).

Close to harvest leaves curling, crispy, yellow tips
The leaves of some of the main buds are showing problems. The tips are curling/pointin up and crispy and have yellow/brow tips. The leaves also seem to be showing big spots but the color is difficult to see since the leaves are grey/purple/brown the spots seem greenish/yellow

Brown spot on leaves
I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis. Someone could help me?

Does anyone knows if should I flush the pot ahead of time to reduce nutrients levels?
As you can see from last pic from week 6, I have used pre amended soil with 2.5 % of Nitrogen on dry mass. (sorry for the italian). Should I flush the pot ahead of time in order to reduce nutrients level so to both solve the yellow tips problem and favour the flowering stage?

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.
I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!

I don't think this is nute burn...
So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

Leaves burned after spraying a cocktail
To repel aphids I sprayed garlic infused in alcohol with water, already did this few times without side effects. But this time I added several drops of tea tree essential oil. Is it possible that the essential oil has burned the leaves so much or is this some nutrient deficiency?

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)

should I be worried?
I have a problem identifying the cause.I notice that the lower leaves become dry, crunchy lose their color. But only the very last leaves at the bottom. I do not notice any problem towards the apex. Does anyone have a lead please? An excess of P ?or K?
