Will these parameters ruin my crop?

A question of a fellow grower:

I have a grow with 12 plants in Week 8 of flower and the tent is just getting hotter and hotter. So much so that I cut down to just 1 of my 2 600watt HPS lamps.

The trichones on the 3 strains, Bubba Kush, Kandi Kush and Blue Cheese are still clear but obviously on the verge of harvest.

I have a dehumidifier going full blast, 4 fans on the floor oscillating and 2 above the canopy also oscillating as well as my intake fan and outlet fan going full blast!

I’m averaging 26°C Temperature and 48% Humidity over the last 6 days.

As the temperature rises outside over the last few week I’m struggling to keep temperatures down.

Yesterday in particular the tent was 27.3°C as it was a beautiful day outside;

I live in the south of Spain.

Trouble is I leave for a trip where I’ll be gone for 3 days and worry that I’ll return to a disaster.

Will these parameters ruin my crop?

I bet your carbon or charcoal filter is clogged and causing the higher temperatures i run 2 600w hps mh lights in a 4x4x6 grow tent and when the temperature spike up its time for a new charcoal filter. My plants grow just fine from 79 to 93 degrees on a very hot day outside but I don’t see why you couldn’t do well with what you got going
