Last week has been over 100 and a few days over 105 F - making sure they have enough water (drip + supplemental hand watering) and no problems I can see.
Last week fed ammonia on two days (each dose = 20 ml/gal/plant) and watered in 25 g struvite powder each plant one time.
These plants stretched 12 inches in one week with hot weather, clear sky, but also less wind.
