Brown spots

infamous8803started grow question 4 years ago

I'm having what I think is a cal deficiency. Ive been using calmag for a week or so now. Just curious if this will ruin my end results? It looks pretty bad. Buds still look nice though. Any thoughts?

I too had a very similar problem and I also thought it was a deficiency, turns out it was a lockout. That late in flower, it's probably your case too. Perform a slurry test to know your soil pH and flush it. Cut the dead leaves to know if any new one appears. Hope this helps.

Looks like you right.It won't ruin it but it won't help it.Get some Amino acid with Kelp/seaweed if poss.The calcium intake goes up 300-1000%.Calcium is one of the main buidling blocks to life.If your not using extra PK then make sure you get some.

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?

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?
