One of the plants I have is showing black spots on the lower leaves. It starts out as a copper color, then copper, and finally black, spreading pretty quick. Other then these leaves, the new growth and the rest of the leaves look pretty healthy. Should I trim these leaves off asap?
I was thinking it might be a phosphorus deficiency. It just seems early to be showing a deficiency problem, unless I have a pH problem. All the plant's leaves I have are curling under, looked a bit like symptoms of overwatering. I haven't watered for about 4 days now and some of them seem to be flattening out.
The seeds are freebies that I got with my order. They were started in Jiffy plugs which I wish I didn't use now, and that may be leading to any pH problem I may be having. They are in 3 gallon grow bags with Fox Farm Ocean Forest and perlite. The temps are between 65 and 82F. Humidity is between 35 and 62%. I was using filtered water for the first 15 days or so and have switched to distilled. I haven't been able to test the pH yet, that's really the most important thing I need to do right now. The seedlings were started under CFL's and moved 20" under the HPS a few days ago because I transplanted them into the 3 gallon grow bags. I now have my MH and have changed the bulb.
Also I have noticed that most of the stems have a clearish covering that has pulled off of them. Almost like a plastic casing. This may or may not be related, but I thought I would include it anyways.
Any help would be appreciated, thanks!
