Leaves curling, turning yellow! (Platinum OG)

Hi. I'm only a novice grower, but today I noticed that one of my plants was looking unwell. Here are some pictures:

Please excuse the somewhat poor camera work.

As for the plant, it is currently being grown outdoors in Southern California, where its ~105 every day during the summer. It receives 36 minutes of water per day via sprinkler tubes and emitters (12 minutes 3 times a day, approximately 7, 12, and 6). It was planted in April, and as can be seen the flowers are beginning to form, but they are turning a (unhealthy?) brown color. The soil is Fox Farms brand, which is known to be high quality. The only recent change I have added was Alaska Bloom Fertilizer (Alaska Mor Bloom 32 oz. | Plant'It Earth (R)).

I am extremely worried. The problem doesn't appear to be overwatering because of the amount of yellow leaves, and shouldn't be sunburn because of the shade cover (green cloth seen in the background). Last year my Platinum OG plants did not perform well, so it is possible that this strand simply does not like my environment.

Thanks for any and all help

Bumping for urgency! :sadcrying

you will get a much better response...! Sorry, I dont have any helpful info.

i dont see any nute burn or any other sign of poor nurishment if i was to guess i would say it is just the high heat and low humidy and/or really high ph balance in your soil. the ph is where to start looking for the problem and then go from there

To much WATER!!!!!!
