- fine-ass '22 harvest!
:Cheers:....solid input guys!
Kaellen- big picture stuff: different strains, auto or photo', often have significant differences in their nute' conc. preferences... some can tolerate high feeding rates, others totally hate it-- and show it!... as mentioned, coco need pH's in the upper 5's-low 6's,... even a couple tenths off can be an issue (think more like hydro' than soil),.... Details: symptoms on two of those plants are really advanced,...caused by nute' burn and a likely nutrient lockout related to the pH and/or the sheer amount of nutrients in the media at this point... Nute' defc. can be caused by: a) sheer lack of a given nute'; b) pH lockout which renders a given nute unabsorbable, even if there's plenty of it around; c) too much of a certain nutrient can interfere with the uptake of others (i.e., too much K can mess with the uptake and availability of several other nute's).... the latter two are likely what's going on here.... *** ...follow what HH says about dialing back your conc.'s, and get that pH down (vinegar or lemon juice, if you don't have a dedicated pH down product), that run-off pH and ppm is a bit alarming,... I would recommend treating the coco with a clearing agent and flushing, especially this close to harvest,... too much stuff in the plants at that point will make for nasty smoke!
