Phosphorus deficiency?
PenguHBstarted grow question 3 years ago
Sugar leaves turning pale/yellow(?) from leaf edges. Seems to only be happening on main colas. I suspect phosphorus deficiency. Beginning of week 4 of flowering, fast groweing auto (around 2 weeks left according to the breeder).
Please help me identify the issue.

Servus Mate, i'd rather increase the distance to the light before u change anything at your feeding regime. Could be also too much/too close to the light.
Good luck for the rest of the way 🤞

The picture taken in normal light (the only ones that should be posted!) show a plant with no deficiencies that I can see, but the leaves are very green, indicating too much nitrogen. Grow light images can be rather distorted colour wise, leading to potential a misdiagnosis.
Going by the pictures, you are also still at least 4 weeks away from harvest.
Hope this helps, Organoman.

If your feeding at a ph of 5.8 then that is a problem. Dirt grows should be closer to 6.5. Your phosphorus uptake would be pretty near nil at 5.8. Cheers

Calcium deficiency, cal-mag now in hand, water now, or wait for normal scheduled water? Last water yesterday.Plants are suffering from an early stage of calcium deficiency, received a bottle of cal-mag today. Watered last night cause I didn't want to wait any longer. Should I wait for my next water (2 more days) or give a single dose of Cal-mag now, to get some calcium to the plant?

Deficiency or ending cycle?Hey!
I was hoping someone could tell me if the first plant has a deficiency you would recommend I correct or if she is slowly coming to an end of her life cycle and I should just let her fade?
The last picture is my other plant, less severe, but same question :)
Thanks!

More rusty spotsSee this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing.
Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.4 years ago

Rusty Leaves3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera.
I also have slight "clawing" on many of the upper leaves.
Mg/Ca lockout because of nitrogen toxicity possible?
Doesn´t seem to be fungi, as there are no spores to rub off.

Nutrient burn or deficiency?I’m seeing brown spots that resemble a calcium deficiency but I’m feeding them cal mag:s
One of the tips on the new growth looks burnt so it looks like i may be feeding too much or immobile deficiency?
I’m feeding about a 500 ppm of newts. Any help is greatly appreciated.
