Demanding More N?

GrowingGrannie is 💯 percent right. Nute lock. Humic/fulvic acid to chelate those locked out nutes. Got to pH, we all learn the hard way, I sure did. I started using much larger pots and going proper living soil, getting soil tests from Logan Labs, and dialing in the pH, bottle nutes have its own challenges as well. Best of luck and will stay tuned!

the plant you see on the first picture is an afghani during the final weeks. I always fed them with at least 0.2 EC calmag first then add nutrients. it was all green yesterday and today I saw her like this. With this grow I didn't adjust the ph almost all the time because people say ph up or down products mess with the microbial life and the microbes have the ability to lower it but not raise so when I see pH is between 6 and 7.5 ı just gave it to the plant and lately in the flowering as the nutrient solution changes I started to see multiple deficiencies. I think it's pH causing all of this

not the right progression.. that is starting as interveinal and not creeping upward. several things cause interveinal chlorosis. i would wager Mg-deficiency... those actually occur 4-6 weeks before any visible symptoms.. this is a tidbit you can use while reviewing past notes and feeding regimen to eliminate the possibility. also, you need to look back more than a month to know if this is why... or to relate it to a change in beahviour at that time related to Mg etc etc... i also see a little autumn coloration in a leaf - little red in that first pic... so the plant is at or near senescence stage. it may just be dying, though the pic3 clearly shows it's nowhere near the end. so, i'd definitely tweak your feed a bit as the canopy has a ways to go yet before it can go kaput. The last pic does look like N progression -- bottom up and tip-in. So ensure pH isn't a problem. when i see more than one symptom it's typically an imbalance of nutes with one locking out others or pH swing potentially doign the same thing. or, may jsut need both N and Mg. (consider the progression of the leaves seen in 4th pic given here.... if that started as interveinal, ignore the N-def option... N deficiency does not start as interveinal chlorosis.... it can sort look that way further into progression but the order in which it occured matters)
