Brown spots and yellow tips in flower, started around wk 8-9. Thanks!

Es un bloqueo también tiene exceso de nitrógeno Tienes sales solidificadas en las raíces y no puede comer bien es como si hubiera un filtro que impide que coman correctamente Yo utilizo un rompedor de sales con los fertilizantes para evitar este problema tan común ( no lo confundas con un arrastrador de sales no tiene ninguna relación en su uso ) Un saludo amigo Much løve 💚

Thanks m0use. I ph every time to 6.5 or a little under but I should prob be checking my runoff, I guess? Could it be under-watering (I typically water on a WxFxW schedule throughout)? I also used Recharge up to about wk 9. Could it have something to do with cutting out 4-4-4 for the last top-dress, and only using 484 and Fish Bone Meal? So maybe underfed? I'd love to go with DtE but I've gotta figure out what's happening in mid-to-late flower- same thing with a 1g CDLC last month. Thanks again, and I will be switching back to 18-6 with my next run but I honestly think this is something else- showing up so late in flower. I also have read about the usual suspects and causes, but my last idea is that I scratched up the surface of the soil because the dry amendments had hardened some on top of the soil- and as I type that, both of those things seem wrong. Thanks again m0use and anyone else with some specific advice- I understand people feel strongly about a 24hr light sched so- message received! 😬🙏

Also give your plants some down time 18/6 or 20/4 is good. 24/0 is not ideal and can cause little issues like stress and overall unwell look to the plants if everything else if not locked in.

Might be a PH issue. I like to correct my waters PH to 6.5-6.8 when using dry amendments. When I grew with out using a PH meter my pants did what yours are doing now. They will finish flowering and be good but cant help but think if they could have been more. Given the relatively small planting space/pot for a large plant its harder for the microbes to keep PH in check, this gets more complicated with more amendments getting mixed in that alter ph as well. I also like to add in extra microbes in every other week to help boost the soils bioavailability/population. As a side note check the underside of the leaves for eggs, not saying they have mites but some of the markings are mite like on the leaf structure. Good Luck!
