[New Grower] Brown Spots On Lower Leaves

[cannabuzz]

Hey Guys,

I noticed two of my plants (15 days old have brown spots on the lower leaves and another has a "crispy" dry tip but it's still green. After doing some reading around the internet I attribute the brown spots to calcium deficiency. Is this correct?

Someone in this forum warned me to watch for possible over watering with one of my pictures I posted. Could this be a reason for these symptoms? If so, What is the best remedy for over watered plants?

I've also been dealing with temps getting a little warm inside my grow tent. I've been able to lower temps and keep the tent cool but can't find a way to raise humidity. Can this also be a reason for these symptoms?

Any advice and/or suggestions would be really appreciated

What's your medium? Is this soil? coco-perlite?

It might be calcium, you should have some anyway - I mix lime with my soil for constant Ca supply but you can use cal-mag in your water.

Your plants do not look over watered at all.

When you raise the temperature of the air you lower the humidity, that's how physics work. Increasing your ventilation will change the air faster and an air circulation fan inside the fan will decrease hot spots formation.

They look good, keep up the good work

Thank you for the reply

I'm using Fox Farm Light Warrior Seed Starter

Do I mix the Cal-Mag with the nutrient water?
