Purple leaves on seedlings??

Hey again, im using Liquid Karma on my seedlings, only a week old, using 5ml per 4 lts of water, im having some purple spots appearing on the leave tips, any suggestions???? and yes Liquid Karma is purple

You shouldn't be using nutes at such an early stage. I would stop using nutes. It might be nute burn.

agreed. if you used soil with nutrients added....I.E. Miracle-Blo. twice the problem heh.
