I'm thinking it's heat, or bug issues. Everyone always says nitrogen defeciency when they see a yellow leaf, but I just don't want to believe it. What do you think it is? Honestly I don't know. Please note each picture/leaf is from a different plant. Four in total.

I use tap water I don't have a job. If it is a defeciency I got nitrogen covered. I have fertilizer, or I could use used coffee ground's. What does eggshells give again? What can I use around the house for cal/mag? If it helps the stems the leafs grow on are a little purple on one side. Also I've only nuted once with some shultz 10-15-10 It's miracle crap soil.

i think eggshells are a source of calcium...but the shults should be good enough, maybe flush it and make sure you got no build ups lockin out any micro nutes, repoting it never hurts either..

It looks like some of the new growth is healthy and green correct? That being the case I think we can rule out nitrogen deficiency. Could be nutrient lockout from PH. You mention heat issues? What are your temps? Have you sprayed them with water under direct sun or HPS lights? Could be the cause of the burnt brown spots. The yellowing and brown spots may be separate issues.

Purple stems are a sign of overall nutrient deficiencies in my experience.
