Dark brittle leaves

DougJitsustarted grow question 6y ago

I have noticed my one plants leaves are very dark and quite brittle. Like they are breaking/cracking on the actual leaves quite easily. What could this be from?

You are so far into bloom i think it doesn't matter. If accompanied by blue-green leaves, it could be a P-def. LEaves don't look like this... the purple i see is more likely senescence / autumn related colors. leaves look a big glossy, maybe? I'd wager some minor lockout. Whatever it is, a minor adjustmant would clear it up i think. if you calculate ppms from guaranteed analysis labels, you can make a more informed guess.

DEFOLIATION: when should I do it? I start by removing some yellow leafs and I'm at 2 week from harvest. Should I remove the other biggest leaf, even if they didn't shadow the flower and are healthy and green? Also, what means if the stem is reddish?

I'm not sure what's going on, but the tips of several leaves are twisting over and/or turning white. I don't know if it's a nutrient deficiency, nutrient burn, I don't think it's too much heat, but maybe due to sun burn? I'm not finding much luck about white leave tips online.

Holes/Spotting on leaves Noticed some holes and some spotting on a few leaves. Initial thought was spider mites, but based on pics not sure if that's the case. Also thought it could be areas where water beads were on the leaves and burned through (as the holes go). Not sure about spots. Thoughts?

Problems showing up in week 5 flower I have a problem developing and showing signs through this week. Looks like at least a calcium and a potassium deficiency in one plant and a another deficiency just starting in another. Not sure how to fix this. First 8 are one plant, last 2 are another.

Leaf spots Hi guys. These spots have formed on the lower leaves. Is it a cal-mag deficit or maybe is it due to strong airflow? Also, are they already big enough to switch to 12/12 light or give them another week? Thanks!

Leaf Mutation After Topping?So I topped this 10 days (ish) ago. The leaf mutation, I'm wondering if it's actually where I topped it. What do you think? I think cut it pretty damn clean to be honest. I just want to figure out why the leaves are this way. 🍃✌️

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?

My upper leaves? Is this light scald? Or a nutrient imbalance? This has been coming on over the last week. The older shaded fan leaves appear healthy. Also the one bud on the far leftside, furthest from the light is less affected. Her tent mate gets the same light and nutrients.😕
