Welcher Mangel oder Überschuss ist das?

sieht mir nach Kalzium Mangel aus......bzw.kontrolliere mal dein ph-Wert....... mit Calmag bekommst du das Problem in den Griff.

Alot of root causes as to why you might be suffering from deficiency. To simply assume she is deficient and nothing else is wrong is almost as bad as doing nothing. Majority of problems related to Ca and Mg are often environment related, skewed ratios or ph imbalances. 🤔 if your not resolving the root problem then your just 50/50 throwing more gas in a car doesn't fix a broken engine. Sometimes it does though. Feed more cal mag, when she doesn't get better start looking at environmentals, soil saturation, transpiration, ph, ec looks to be close to the line too.

Hey growmie, that looks like a phosphorus issue to me. That rusty spotting and yellowing this late in flower usually means the plant’s struggling to get enough P. Could be pH drift, if your runoff’s dropped too low like under 6.2 , that can lock it out even if it’s in the soil. Night temps being too cold can also slow P uptake. It happens a lot in the last few weeks. If you’ve still got a bit of time before harvest, you could give a small bloom booster, just something gentle. But if you’re nearly there, I’d just let her ride. Buds still look decent and this kind of fade is pretty normal late in flowering.

Too little magnesium. Seeing deficiency not toxicity. Your diary doesn't show calmag in the mix. Epsom salt can help with magnesium issues. Or Phosphorus. Were you still feeding your veg mix and not flower mix? All of this could also be an uptake issue because of PH.

Calcium and magnesium deficiencies. Waiting this long before seeking advice means there will be little chance of restoring the plant to full health before harvest date.

Hey there I know for sure 100% the problem and the solution The soil ph is way to low causing lockout when you water if you collect some of the run off water from the bottom the pot and check the ph it will be down around 5 or below The solution is simple if possible take the plants to the bathtub and run about 5 to 10 gallon of tap water thru the soil most tap water is ph around 7 to 8.5 this schools being up the soil ph and wash out any old nutrients in the soil make sure after running all the tap water thru the soil to water a few cups of water with nutrients after the tap water so the plant has some nutrients to absorb the tap water is just correcting the soil ph so the plant is able to absorb nutrients Good luck if you don’t fix the problem you will start to get more and more of those spots all over the plant

Sieht nach Kalziummangel aus. Calmag gegeben?

Also sieht für mich nach CalMag (Calcium/Magnesium) mangel das ist ein typischer Mangel wenn man unter LED Lampen growth. Kann man einfach kaufen und bei jedem Gießen dazu geben, ich nehme denn CalMag von BioBizz, was du aber auch in der Blüte dazu geben solltest wäre ein bißchen PK (Phosphor und Kalium) das hilft den buds das sieh schön dick und groß werden.
