Calcium and magnesium deficiencies. A cal/mag supplement will stop this from progressing. Now that you plant is flowering, you need to cut back on the nitrogen (the leaves are super green!), otherwise you can end up with leafy thin buds.

Spots on leaves Anyone know what's causing this? Slight discoloration and rust spots, mainly on older leaves. It's not that bad but quite spread out. did spray with neem oil recently, so is it just burn spots or a nutrient problem?

Copper spots I noticed these copper spots and leaf tips about a week ago, it doesn’t seem to be progressing too fast. The plants otherwise seem to be healthy but what is the issue? Magnesium Def?

Many or low nutrients?Hello Growers What could it be? I thought it would be a nutrient deficiency (EC-1.0) so I picked up the nutrients to EC-1.4, but it's getting worse. Do you think they'd have a lot of nutrients?

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?
