Brown and straight with spots is potassium deficiency signs. Also check pH in substrate to ensure it is not a lock out front that. If that is is range then I would increase potassium level.

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?

Leaves curl, become crispy and have weird colors
I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

I water with 50% distilled and 50% rain OR 50% distilled and 50% tap. I have fed once with Grow Big and it happened right after. Might have rubbed nozzle on the underside of the leaves. I water every 2-3 days and water until drop of runoff appears in tray. How much runoff?

Brown spotting?
Hey everyone! My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean? I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

Why leaves brown? (urgent)
Some leaves turn brown as in the photo. Leaves in the middle turn brown first, then bottom leaves. Now I try making larger lamp-to-plant distance and feeding less nutrients, but no good sign appears. Other conditions are stated in my diary. Why do you think it is?

Light burn?
I had lowered my Sanlight Q4 from 50 cm to 40cm, as per vendors recommendation and now I believe that I have burned the little ones. Or is this a nutrient issue?

Leaf spots!
Leaf septoria or nute deficiency? Don't have ability to monitor pH or ppm. Do I cut the affected leaves off or any other home brew solution? 3 different plants in the photos.
