Brown black spot crispy edges

I need help! Northern Light has Reddish brown spots turning dark-gray and crispy dark edges on the top leaves! It looks like a different issue from week 6 where gray spots appeared on the bottom leaves? Any ideas? Thanks

Looks like you have or had a calcium deficiency. When you grow under led lights the plants need more calcium. Best of luck the rest of the way.

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.

Heat or deficiency? Or something else?I'm noticing some sort of deficiency or toxicity. I need help on figuring it out. I water with distilled water, cal mag, and 1/2 strength bloom boosters. Ph @ 6.5. Could it be heat? It gets a little over 80 F. I have AC running, It's still cooler than outside in the sun though

Yellow leaf edges I have a couple plants that are about 5 weeks old, and one has started getting yellow edges around the leaves. I feed them with worm tea, kelp, and calmag every other week, but it's a light dose so I think this is a deficiency and not a toxicity.

Ongoing brown and yellow patches forming in week 6 of flower I've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)
