To much heat and to much light maybe. It’s light stress/heat burn with a little to much nutrients maybe. Stop using calmag if you do that

What is this deficiency?
Some leaves are burnt but the ph is good, watering is good light and temp good soil seems good and balanced. The humidity is very low can it be because of humidity?

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?

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?

Nutrient deficiency which kind and/or light burn?
Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.

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!
