The big issue with plants that are too big for la casa is soil chemistry becomes hard to control. Any issues you may have, however small, are magnified. Your night temps are low, for example, and if the soil is quite wet, you will see lockout symptoms quickly.
I don't see how much drainage you have in there but one way or the other, you are going to want to get it into a larger pot of fresh soil.
And a last question, how long has the plant been in that pot? Nearly all commercial potting soils are pet-based, and after the soil has been used/watered for 6-8 weeks, they often start acting funky- pH becomes harder to control, and the structure/water retention properties of the soil itself change.
stinkyattic Reviewed by stinkyattic on . #@&$!!! N? or K? or? What is the deal with these 2 plants? they are 25 days into flower, and on one the lower leaves are starting to yellow...which might be a N def, but unsure since it has those black spots on them. On the other, the whole plant is a lighter green with purple stems, and also has some dying leaves- but looks like something completely different. First 2 pix are one, second 2 the other one.
