Calcium deficiency. Add some Cal/Mag to your fertilizer line up, or if using it already, increase the dosage. Affected leaves won't recover, but new growth should mainly be fine once this is done.

To defoilate or not to defoilate.. that is the question!I've always heard that you shouldn't "defoilate" auto flower cannabis, especially if they're a sativa to boot. With that being said, (looking at my pics for reference) should I do more defoliation? Would doing so really increase my yield significantly? Thanks

I have symptoms of both N deficiency AND toxicity. Paleness is spreading up from the lower leaves, but there's also downward clawing & "burnt" tips on other leaves. Plus some weird brown ends on the larger fans. Haven't fed any bottled nutes. Halp?

Help!The leaves are limp.. could anyone diagnose the problem of these plants? The leaves stand down, both when the pot is full of water and when it starts to dry. Could it be an excess of light or a lack of air? I had the inlet fans at idle!

Leaves yellowing These leaves are stressing me out. I’m not sure if I’m having a lockout or if I’m not feeding enough phosphorous. Either way, I’ve been using 3 ml/gal of tiger bloom, 3 ml/gal formulex, 3 ml/gal big bud & 1tbsp of molasses for feeding. What do I do ?

Bound and wrinkly leaves Some bottom leaves are wrinkly and where bound to eachother. These are new growths that grow from first 4 leaves. I'm having hard time googling the issue. What could cause this and should I be concerned? Last picture is before I split them.

Twisted leaves I have some twisted new growth. The only other times I had this problem was when I had broad or russet mites. Am I being paranoid or could it be again? Any input would be helpful.

Removing dry, necrotic leaves Should I remove the dead part of the leaves? Specifically remove the brown parts of the leaves and leave the green part to save them for trim? If so how could I go about removing them without getting brown crumbles everywhere?

First true leaves deformed and white parts sticking out. What’s going on?This is a Dutch Passion Auto Brooklyn Sunrise, germinated in a paper towel then transplanted into soil. It broke through two days ago and after the seed hull dropped revealed two white parts coming out of the ends of the somewhat deformed first true leaves. Never seen this before
