K deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?

Magnesium deficiency, not potassium defciency.
In soil grows, a pH of around 6.4 is ideal, 5.7 in soil is way too acidic.
grownotstopanswered grow question 2y ago
Hey! Do you monitor the pH of the water? It might not be right, and the plants aren't efficiently taking up the nutrients from the soil. The value during those weeks is usually around pH 5.7. Fertilization is probably not the issue since they look good from the center. Check the temperature and humidity levels; it doesn't look too serious.

It looks like a K deficiency. Could be a possible lockout of K .

Deficiency?Hi, I've encountered some deficiencies in my plant but I'm not sure whether it's Magnesium, Potassium or anything else. I'm using the BioBizz outdoor trypack (BioBloom+FishMix+TopMax) Currently 2ml/L each. Symptoms are shown in the lower leaves. Maybe CalMag? or Pk 13-14? pls lmk

Leaf diagnosis: nutrient burn or deficiency (or both)?he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy

Dying leavesI had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?

Harvesting a struggling plant or just letting it fightCan she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me.
Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.

Yellow and crusty leavesHey dear community,
Why is my plant not recovering? I even adjusted the ph of the watering and add cal mag. Every week it’s getting worse and I don’t see any improvement. I use the fertilizer from Bio bizz and light is far enough away from the plant. Temp and humidity are fine

Growing in FFOF with some HF but have nutrient issues...have only given CalMag with RO water and this is what I've got.Wedding Cake nute burn or possible P deficient with yellowing slightly down the edge? Also may have N toxicity with curling leaves? Blueberry also has slightly burnt tips, both plants have yellowing in the oldest growth. All in diary pictures. Thoughts? And how do I fix it?

Discoloration and burnt edges on leavesCan someone please help me diagnose this problem?
At first I thought it was root dry spots from the drip watering system but it’s gotten worse.
The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves.
Anything helps, thanks!
