Day 14. Since day 12 a brown spot has appeared on one of the leaves of the first node, spreading little by little. Because of the symptoms, I think it's septoria, so I've sprayed neem oil to see how it works for her. Someone knows what can it be?

Deficiency/Light Stress Issues
What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

K deficiency? Or something else?
Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

Leaf issues with 3 Pineapple Express Autos - is it burn or deficiency?
All 3 plants are having issues to the lower leaves. They are dried and brown blotches, brown edges of the leaves, leaves drooping off and curling down and brown. They switched to Canna Terra Flora two weeks ago - is this a over feed or deficiency?

Unknown rust on 7th flowering week
This started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?

What am I looking at?
Redish Brown spots, and slight discoloration. Magnesium deficiency? Calcium? Other? Gave them a splash of Calmag, but was it even necessary? OR, should I have just swapped nutes and wait, then correct if not improved? (It was nute day, that's why I ask!)
