Always something new to learn… I have 2 plants, mid flowering and noticed one of the plants leaves are yellowing. I plucked one of the leaves…see attachment. Is this nutrient burn from anyone’s experience/expertise?
Not all leaves are this color. Just the larger leaves.

thanks

is Ph, temp and humidity all in check? The plants are drawing nutes from the leaves anyway so they are not getting what they need from the roots

Every watering and feed I check PH going in out out. PH going in has been 6.0-6.3 and the water out has been within the same range. Temp range has been 79-84f and humidity 41-48%. Interesting thing is when I test soil pH day before watering it reads around 7

Needs more nitrogen and/or cal mag

I was using cal mag during veg then I stopped when I switched to flower since my understanding was less nitrogen required in flower. The feeding I am using during flower is 2-8-4

Also probably need more potassium at that stage of flower.. and the way the leaves are cupping makes me want to up humidity a little more like 60% would bring into a good vpd range
