My plants started having some health problems. Their growing in a dresser i carved out in my attic. Heat is a lil high. Slowly though all my plants are getting health problems. I can see problems in the leaves. Burnt tips, one is plant the leaves are curling up, red stems, brown spots, yellowing of leaves, one has like light green or yellow lines and some circles on the leaves. I am wondering if they need nutrients even if they are only about 2 weeks old, but I don't want to nute burn them. Also I am using Miracle Grow Organic Soil. Would it be ok to give them the nutes it looks like they need or would it be best to just wait it out.
