How long has your plant been flowering? A lot of those lower leaves will turn yellow and die off because they don’t get as much light and your plant is using the energy to grow buds. Cut the yellow leaves off, if you’re still early in flowering add a fresh layer of soil it should have enough nutrients to get you through

HI Thanks for the reply. First time growing; plant has been in flower almost 2 weeks now. What about Cal/Mag supplement? Since using super soil, (came in the grow box kit) was told to use water since the super soil had all the nutrients I needed.

1 tablespoon of unsulfered molasses mixed into a gallon of water once a week should work

I have never used what is called a super soil. But I have used ocean forest. It is good stuff but will deplete itself after a while. My guess it is starving. It is consuming old leaves to feed itself. Just like the cotyledon leaves of sprouts. Newer leaves are often a lighter green, however I am not sure the mid plant leaves with yellow is feed / nitrogen deficient related. Some of the leaves look like it is from a pest of some sort. It looks like tracks left by leaf miners

Thanks. Super soil is super duper stuff with all nutrients in soil. It’s the bottom layer of dirt with the ocean forest on top. Suppose to “water only” as it has all the nutrients your roots need for your grow. I don’t know if that is what is happening to me but I believe these plants need some “bloom” nutrients. Thanks for the support
