Hi Alan
I messed up. I gave my seedlings some "Terra - Grow", which caused Nute-burn. I identified the problem, flushed the girls and waited for some green leaves to grow at the top. They were about 4 inches with a few sets of leaves so decided to give them a few drops of Terra-Grow once again.
It seems I've gone ahead and burnt the seedlings AGAIN...
When do I need to add my fert? I mean, how BIG does a plant need to be before it NEEDS to be fed nutrients? I was told the growing medium has almost 0.0 nutrients in it. I think it was coco.
