Strange yellow spots

According to your log your pH is a bit high.. this can cause a lockout of iron which it looks like what its doing.. shoot between 6.0 and 6.5 if possible! Cheers and happy growing!

Leaf Discoloration - Hopefully NothingI'm looking to rest my concerns that these removed fan leaves from lower/center canopy are not simply just appearing so due to lack of light and prior plant tie damage.
Focus on the yellow/brown discoloration, actual physical damage is accounted for.

Yellowing and light green leavesHello growers!
My AK has been getting some yellow leaves, big fan leaves and small new leaves at the bottom, and looks less dark green. Is this a deficiency (looks like nitrogen but I don't want to give it even more nutrients) or is it just self defoliating? Any ideas?Week 6

Over watering? Asked a similar question before but want to save this plantThis has gotta be overwatering, right? The soil + pots I'm using don't seem to drain very well. Started drooping like this when I added a humidifier at around 70% relative humidity. Maybe pushed it over the edge? Going to home depot. Perlite? Change out the soil? Better pots?Leaves. Curl down

Late Flower Rapidly Yellowed LeavesThe yellowing leaves have definitely progressed quite a bit in this last week. Does this look like a normal natural late flower nitrogen deficiency? I still want to flush the plant, wondering if I should start the flush now because the leaves are already starting to get yellowed.Week 19

Como evitar el amarillamiento de las hojasEn los 4 cultivos desde que empece, casi siempre tengo este mismo problema.
A partir de la 3-4 semana, las hojas empiezan a amarillear desde abajo y va subiendo por la planta.
Por lo que he leído, parece una deficiencia de N, pero nunca consigo arreglarla.
Consejos?HELP PLEASE!😇Week 6
