Rusty brown spotting on upper fan leaves, too much Tiger Bloom or deficiency?
puppetmaster77started grow question 4y ago
Hindu auto, week 11 started seeing rusty brown spotting on upper fan leaves. At this point I was only using tap water and 4 tsp/gal of tiger bloom. That is aggressive so I backed off to 1.5 tsp. I watered with cal mag 1 tsp just in case it was deficient. Ideas? Buds seem ok.

I wanted to say it’s calcium but when the leaves turn like that it’s too much sauce, it’s nuts burn for sure, ease up on those nutes! Looks good though!

Looks like you have a phosphorus issue. I would check your ph. Phosphorus availability decreased with increase in pH.

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!)Leaves. Color - Dark-brown

Possible P Deficiency?Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.Leaves. Color - Dark-brown

Brown spots, serrated edges curling up - calcium deficiency?This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up.
Is this just a straight calcium deficiency?Leaves. Curl up

Hello fellow experienced growers, is what I see on this leaf, combined with a reddening of leaf and main stems really signs of a CalMag deficency?
Or do I have another problem?

Continuing calmag deficiencyWhat I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciatedLeaves. Veins - yellow between

Grayish brownish fuzz on sugar leavesTurned my northern lights plant around today and noticed this on the back of it. Yikes! Is it bud rot, pest damage, something else?
