I just saw a few tips burnt and others become yellow from the edges.. I was really watering bad only 250ml per day in 12L pot with low humidity do you believe thats the problem? Also I saw a few red stems.. do you believe this could happen from this? And not any nutrient lockout? I am so much...
No it didnt happen overnight, but i searched and found that pk toxicity could block absorption of macros thats what i thought... Because mostly new growth is affected and interveinal chlorosis started to appear as you see on photos
