I started my TG a few days ago and today there are black spots developing on my two kale seedlings. Any ideas on what this could be from? TG is strictly indoors with grow lights on 14hrs, off for 10. Running half strength nutrients 15 mins on, 45 mins off. pH is sitting pretty consistently at 6.0.
Hi jennaraeb, All is well. Looks like those spots are on the early leaves (cotyledon) which will quickly die-off once the real leaves form. If you are concerned, carefully snip the offending leaves off with scissors. Otherwise, just leave 'em be.
