Anyone know why the leaves are turning yellow with black spots? This all happend in the span of 3 days.

Overwatering for sure 😕 More info: https://www.mrgrowit.com/post/over-watering-cannabis-plants

no prob remember less is more . esp when adding nutes . monitor ph levels of the soil runoff . all the nutes in the world aint worth a dam if improper ph wont let them be absorbed . she's still just a weed dont over adjust & be patient

if you can put your finger into the top of the soil like 1/4 way down & its dry its time to water . i would also advise get a feel for how heavy the pot is when saturated & that will give you a good idea of how dry & light it will become . my guess at this point in there life it'll be every 5 days or so. maybe even longer depending on grow environment temps & evaporation rates .so next time they are dry. saturate until runoff with properly ph'd water, get a feel of the weight & go from there.

likely overwatering .
