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.

What is this deficiency?
They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

Leaves are turning yellow and dieing. Looks just like nitrogen deficiency. I'm in early flower
Losing a bunch of yellow leaves during early flower. I have WPM but it wouldn't progress like this would it? I think I may have just been underfeeding or my pH is off. What do you guys think?

Overwatering or underwatering or other cause?
It's very hot in Rome (30+ degrees) and was away for a week. Got a friend to water mid-way. She gave quite a lot, 700ml. Came back after 3 days, plant was fine. Watered again and after 2 days, leaves dark and wilted. Put in direct sunlight, left for 3 days. Leaves died.

Light burn
I've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.

Is this nitrogen deficiency? Should I change the soil?
Is this nitrogen deficiency? I've been feeding them and using pH Down but nothing changes (pH 7.2). Should I replace the soil? They're in CannaTerra mixed with Promix. I've got some FoxFarm Ocean I could move them to.
