I noticed yesterday that the tips of a couple leaves were looking burnt, Today when I checked on them they were about the same, that was this morning. I just checked them now and within the last 2 hours this has started happening to the plant. They are in soil under Fluoro's. 3 1/2 weeks old. I haven't given them any nutes yet just because I don't have any atm. Can anyone tell me what's going on? Also, I noticed a small insect flying around the lights this morning, just one, and none on the plants at all that I could find. I don't know if this has anything to do with it.
