Hey everyone, so this is my second grow. I have 2 plants, one GSC and other is strawberry cough. The issue though I am having is with strawberry cough. Plants are almost 4 weeks of age from time of sprouting.
Here are the conditions

ocean farm soil
5 gallon pot
So far 2 feedings 1/4 strength of emerald harvest, before that I was just watering with water
RH 57%
Temps 76
pH 6.3
Marshydro TS2000 30inches away from top canopy.
The discoloration I’ve noticed has worsen in the past week or so . I tried to read descriptions of scenarios of leaves turning certain colors but this is more of a yellowish with brown discoloration. I was hoping one of you experienced growers could immediately let me know by looking at the images below.

my assumption is some kind of Nutrient deficiency?

if you mean ocean forest soil, you don't need to feed that soil provided you use large containers. I don't know if 5 gallons will be large enough but that's better than just 3 gallons. also, the brown areas look like heat damage. could that be possible?

I have minimized the wattage to 75% from day 1 and have always been 30 inches away according to manufacturers guidelines

I’ve seen that “rust” like damage from cold humid air intake and temperature swings.

Whenever I’ve had it it’s been autumn or winter and just dropping a ceramic tube heater in the room to come on an hour before lights off and stay on an hour after stopped it.

You’ll lose the affected leaves but the new growth will be fine.

Just a thought, good luck.

Now that I think about it the air intake opening duct at the bottom of the grow tent is right by plant !

I suggest only changing one thing at a time add some cal-mag in with ur normal routine of watering give a few days if it doesn't improve try something different but I bet its cal-mag.
