Looks like a nutrient lock out coupled with over heating and possible PM??? How is the airflow? Feeding autos at 1/4 strength?

Looks like heat stress. Plants are too close to the lights. Good growing

This is a bizarre one - never seen the spots you got there before.. they almost look like boils or like blisters. Hopefully some one else sees this who knows what that could be.

Feeding at 1/2 strength, temperature stable at 20-23°C. Airflow is on 24/7, got a regulated extractor fan that helps a lot with extra heat from LED.

Yellow leaves near the harvest
This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)

Leaves of young plant are becoming yellow
The leaves of my four week old Stress Killer are becoming yellow from the outside to the inside. I am a total beginner and I read that this may be overwatering, underwatering, overfeeding, underfeeding, so I am confused.
