Deficiency?
Anyone seen leaf damage like this before? 6 weeks into veg in FFOF. A few fungus gnats but no real infestation. Not adding any nutes yet. Really concerned as the plant is looking less green and more yellowy than it did last week.

Brown spots, droopy leaves
I'm trying to figure out what's wrong with them. Leaves look stiff, droopy and feel a bit dry. Am I overwatering? Potassium deficiency?

Flushing don't seem to solve my lockout
It's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout. I flushed 2 days ago but she keeps getting worse. Am I being impatient? I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.

Dry brittle leaves
Discoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

So closing week 7 now and my 4AM are showing signs of deficiencies again. I watered(with nutes) ph'd around 7 past few times and the runoff has still been ~5.9, indicating acidic soil(nute lockout)?At this point, you think it's best I just flush with plain tap water(ph ~7.7)?
