Four identical plants...but one suddenly has yellowed leaf tips...all over

Appreciate anybody’s thoughts. The situation is:

-Four identical plants. Same clones, bought together, started together, treated identically. Same soil mix, outdoor grow.

-Haven’t done any soil amending in 3 weeks.

-Haven’t done any water amending in 9 days.

-Did find mites 9 days ago, and sprayed all four with Lost Coast Plant Therapy.

…but suddenly, one of the four is yellowing on the tips of its leaves.

We DID have some extreme weather this week. Five days ago our heat jacked up to 100-103 degrees for three days. All of the plants subsequently have increased overall yellowing on some leaves, and some scorching on a few leaves…but only the one has gone yellow tip. This started as the hot weather hit. Having a hard time thinking it’s nutrient burn. Maybe just less robust than her sisters?

Your thoughts appreciated!

My first thought was nitrogen deficiency

But just for :poop: and giggles I’ll post a service ticket to get you the best answer.

suggest you increase the fluids to match the increased heat. plant in pic could also use a light dose of nitrogen.
