Im in day 22 of Flowering and the bottom leaves of my plant are turning light green to yellow and eventually falling off.
Here is one of the lower fan leaves on my plant. This happened last time I grew and the whole plant eventually died.
Please help!

From the looks of things its not a nitrogen problem as you would be able to tell throughout the whole plant....I would lean towards MG. but how is the ph lvl of the soil??
